Exactly. I'm not having the problem anymore thank god all I had to do was zip tie the line. I was having a problem with the A/C

 

I'll try that zip tie around the cold side and see what happens. I'm not gonna fight with it no more just gonna observe the vacuum lines and bypass valve. I wish they design the damn turbo like the SRT-4 style with the TD04 with the external bov option. It was easy to work on and less headache.

 

There are some wires that run vertical to the left of the cold side sensor. Zip tie it to those so that it's running in the same direction.

 

can you post pics on that?

 

I did earlier in this thread.

 

oh yeah... LOL

 

Well, over vacation I had a good chance to look things over. I put new plugs in, checked all wiring, did a boost leak test, got my intercooler welded up and reinstalled, repositioned and tightened the clamps for the charge piping and still no fix....I don't understand it....I haven't gotten any codes yet but the power is very unpredictable. What I mean by this is sometime when you go wot, the car pulls decent and other times it seems like it bogging.....I also cleaned the maf, put the stock filter in, and made sure everything is tight. The only thing I can think of is that the gm stage tune hates my car. I'm gonna get the trifecta tune to see if it will make a difference. I'm gonna see if I can get a data log with hp tuners to send to term so he can try to diagnose what's happening.

 

yeah, I blame the tune myself. as soon as I save money, I'm gonna say the hell with my GMS1, and go with HPTuners sinced they are gonna have the fuel tables released sometime soon in August and thank God we have a the best tuner in Raleigh who never had one tune hick up or kaboom yet and everyone has been completly statisfied. But, latetly I never been into LIMP mode for awhile. These were my two error codes P2261 and P206(I think).

 

Well there is nothing else it could be. If it was a sensor, the cel would go ape ****. It's kinda wierd tho how some cars take to the tune and some don't?

 

I'm having the same issues. It's very frustrating.

I cleaned the K&N, the MAF sensor, and tightened the intake all up tight, and the car was fine...no limp mode for 2 weeks.

Then yesterday, car goes into limp mode without a CEL. No power. Car idles funny and rough.
The dealer has no idea what they are talking about, or how to fix it.

 

to be honest I blame it on the PCM being the problem because if its not calculating the same airflow and the car thinks its gonna blow up and so there "LIMP mode" because of its not tuned. Most people who had the same issue with the GMS1 blames it on the BPV tank being the issue for not opening up when it needs to. Mine doesn't go to LIMP mode as often as it used to. So, I don't know what it could be after I had someone checked out the flow charts with the HPTuner software for dianogistics and nothing was wrong with the fuel trims, all he thinks it might be is the BPV the whole time either the cover or the tank for being defective because of the BPV being immature with the P2261. All I have for now is the stock airbox, Injen CP, and ZZP Catless DP. My car has been running fine the upcoming weeks. So, that may clarify the issue. I checked the vacuum lines and everything else and nothing. So the BPV tank could be the issue and that may lead the cause to the turkey gobbling noise you'll hear later due to the GMS1 tune. My future plans are to get the full bolt on's and an aftermarket tune, a dress up, and I'm calling it quits.

 

But if it's the vacuum tank, when you bypass it, it should go away? Right? Mine doesn't, it still does the same thing

Maybe with the mods, it's bringing in too much airflow and due to the gm stage tune not being that great, the car is shiting itself trying to keep up with the flow. The reason why I think this is because when I put my synapse intercooler( thAt i had welded and pressure tested) it seem a little worse.

 

You could be right about the car not keeping up with the airflow and why you may need a tune for it and that's probably why you have the external bov's to resolve the issue to avoid problems with the air leaks and fluttering. I didn't have issues with the GMS1 in first 4500 miles, until I started putting on bolt on's. Before that I had the TWM STS and the K&N drop in filter with no issues with the GMS1. I have never tried the Dejon thick spring to see if it keeps it from leaking pressure due to the high airflows. I'm thinking about going to the thicker spring from Dejon and I heard people who have them never had issues with them. http://cobalt.dejonpowerhouse.com/ I blaming the spring this time around.

 

Dejon spring wont fix the issue. I have it in my car. Taking the car to the dealer tuesday to get sensors soldered and looked at. Also Trifecta tune will not fix this issue either. I also have that. It's a sensor problem. If the issue continues after I take it to the dealer I will let you know. Everything that you guys have done to try to fix it I have as well. 1 step colder plugs made the car run better but i still get the bpv issue, limp mode, spooling immediately after a shift.

 

thank you for notifying me about your issue. a guy in Raleigh told me he soldered his and had no issues since. he said crimping them will possibly will cause the car go into limp mode. what kind of cold plugs are you running and where did you get yours at? I'm thinking about taking my stock ones out, I have a set of used Denso TT Platinum's been pregapped at .40 from the box just chilling. I think they should be at .32 or .35 where the factory ones are at.

Here is a pic of the error codes that 1badblueberrySC picked up from Raleigh with the HPTuners software. Sorry about phone pic.



here is a forum from saturn sky http://www.skyroadster.com/forums/f5/p0236-35516/ who have the same symptons and all have said to "soldered" and that was the cure to the issue. so I might just stop by the dealer and explained about the cause of the issue and they better not give me any **** about my Injen CP and ZZP 3" Catless being the issue to the problem, otherwise I will tell them what they can do with themselves with a 1000 death wishes.

 

I have the one step colder plugs off of the MPx website. www.modernperformance.com.

I also have the dejon spring. I also checked the saturn/sky forums and seen soldering would fix the issue. I have an appointment scheduled with the dealer to get it done on Tuesday at 930. When I zip tied the wire the problem went away, but just recently it has come back. The only time I get the issue is guess what? When I hit a bump in the highway. hit another bump a different issue, hit another bump it goes back to normal. To me soldering it seems like the obvious fix. If that doesn't cure it I'm going to run this car into the ocean.

Nah jking I will just go a different route and probably get a BOV as well.

 

LOL, yeah I live right by the ocean only 10 min out. Got my car on schedule to go in on Wednesday to get the wires solder.

 

that sounds like its wiring for sure... if going over bumps changes the symptoms something is def loose in there! have them solder it and you will be golden i just checked my connections here last week and the dealer took it upon themselves to solder them for me thank god

 

I say take it to the Stealership. It couldn't hurt.

 

I'm taking my car to my buddy next week and he is gonna solder the connections to the sensors so I can narrow something else down. Bill told me that could be the reason why i have lost alot of midrange power... Time will tell I guess. If that doesn't work, I'm gonna see if I can find someone local that I can swap maf, boost solenoid and wasegate solenoids with.

 

Also getting my power steering recall **** fixed. Scheduled that in as well. And getting my tire pressures where they should be for some reason last time I took it in for a balance all my wheels went to 28 PSI....


Edit: Took car to get soldered today. Dealer made me pay another 2 hours of labor as if they reinstalled the kit but w.e. Day 1 of no issues what so ever.

 

Ok I have a question.... If it was the boost solenoid, wastegate solenoid, waste gate actuator or any sensor to do with the turbo system for that matter, wouldn't it throw a code? This leads me to believe that soldering the connection on the sensors may fix my issue.

 

The sensors will also throw a code. P0236 if it's having that bad of a connection. Day 2 btw with 0 issues after getting wires soldered at the dealer. They said nothing about my after market parts. I took it in for an issue and knew the work I wanted to get done so no need to look at other things.

All that stuff will throw a code as well. If it's not soldered and your car is going into limp mode, randomly boosting, bpv is going nuts it's probably wiring.

 

Well, I called my dealer today and the are gonna solder the connections to my sensors on Tuesday at 2:00. I really hope this fixed my issue with the power being hit or miss and all the othe stuff.

 

It should and I hope it works out for you. Another day after being soldered and still no issue. Put the car through about 3 pulls last night on GMS1 and Trifecta still no issues. This is definitely the fix. The only downside to mine is the dealer made me pay to get it done because it was "custom" work and GM says to only crimp the wires in the install.
