its real easy dont worry...

 

seriously, .003 is not going to make any difference

 

it could help

but it would only help if he was having spark blowout at peak rpms

 

you would be surprised.

 

Yes, plugs should be gapped to .032. Also, another problem with the P0300 is that the tune is canned. The IDC's are too short, but that happens with the size of injectors. What's ahppening is as idle the timing is too quick for the injectors. Before the injectors fully open they are receiving a signal to close again. This also has to do with the car having a little difficulty switching from open loop to closed loop. My suggestion is to regap your plugs and get a custom tune. OTTP's tune is not bad. It's only canned. They have a really good tune. It's just that no 2 cars are exactly the same. Each one responds a little differently to anything. Getting a tune specifically for your car will help out, and possibly acheive more power.

 

also on a slim chance... I've experienced a vacuum line left off that tripped the random misfire code, which may also have set off the o2 code... just a thought....

 

is anyone able to explain the random P0054 code? Im gonna regap and check all lines tomorrow after work and hope that works out, but im still wondering about the above code

 

it is a heated o2 sensor code, kinda one of those things if it doesn't come back i wouldn't worry about it, may have just been a soft code since the p0300 threw the hard code to turn on the light

 

As I said before...if the CEL comes on due to the misfire, something is not right. It could be the plugs, or you might have an injector not seated correctly, or an injector wire pinched. Random misfires will pop up on the Interceptor here and there, hell I've seen random misfires in cyl 5-8 on my SS... lol

And BLAZIN, IDK how your car runs, but if its setting off a P0300 CEL at IDLE and you think that's normal...well, more power to you. It's not because of the 60's. It may be the TUNING of the 60's...but I've used OTTP's injector settings in my tuning for 60's and have had no issues.

 

yeah having a flashing CEL is definitely something to be concerned about.

 

60's will cause dormant misfire codes at idle from time to time. i believe his issue is more spark related though. and dont blame my tuning, i have already had to fix one of your bbq specials

its not flashing. that would be a constant misfire that has the possibility of melting the catalytic converter. as i said before, i believe his issue is more spark related.

 

Lulz are

LULZ!

P0300 happens to me all the time., As BLAZIN07SS said, 99% of the time it is a dormant code. Therefor does not throw a CEL.

And just throwing this out there. Remember my car that day at the track? P0300 was cleared. And my car was running BEAST. Just sayin...

 

so did regapping the plugs help out at all?

 

Wow. Did I ever say anything about YOUR tuning? No. Pay attention. And if I recall correctly it was OTTP's tune I installed on Mike and Jamie's car. When you learn how to change injectors...then you can bash. K?

The title of your thread is right...

 

wow, just cause that was the first time i ever installed them on a cobalt. i have probably done it at least 20 times since then. and the tune was still fucked either way. i dont know why you changed the desired map settings that was making the car bleed a ton of boost

 

There was no setting for that on the OTTP tune...that was a table the 05's had that the others didn't. Just like the TQ management that the 07's don't have. The OTTP tune was for an 07.

 

Quit thread jacking!!! Haha I'm heading to shop soon to recheck everything and re-gap... Will let you all know afterwards. For the record the only code that keeps appearing is the P0300... The P0054 has appeared only twice..

And I'm only scanning it after the light comes on... The light keeps popping up otherwise I'd never notice it

so it seems better... The plugs were at .035 and i put them at .032.. double checked all the injectors and they are good... Ill see what happens if i get any cels after this... I wasnt mis-firing much at all according to my scan gauge.. only time will tell

 

good to hear

 

i gapped my plugs to .032 and haven't had a problem with the dreaded p0300

 

You think the P0300 is bad?

Try dealing with a P0101.

Talk about a PITA.

It got to the point to where I said ef it and turned the code off through HPT.

 

07's don't have TQ management ?? interesting ....

 

its just different tables. we dont have complete control over the tq management settings

 

got ya .... thanks !!

 

Exactly. In Transmission settings there are some tables for the 05-06's but not for 07's. Things vary year to year. If you want to see something REALLY interesting compare the 05-06 Stage 2 tune to the 07...


Blaaahhhh... anyway, hope everything clears up and works out for you man.

Jeremy, why did you keep having P0101?

 

I have no idea Terry.

Joshua, Braulio and I went over everything we could think of. And could not figure it out. No loose wires, no loose connections, no pinched wires. MAF sensors were changed. Everything you could think of.

Flashed in a different tune and it went away. So that leads me to believe there was something in my tune that my car didn't like. Something in the MAF scaling and possible PE tables. Not too sure.

But since the car ran like a beast on that tune, I flashed it back in with the P0101 disabled. **** it.
