Okay so my car has been acting up the last 3 months and this is it. I have gone to dealership nearly every time I have a day off and its just a temporary fix.

It only happens when cold stat. It idles like it wants to stop completely but after cold up its 100% fine. I cannot think of anything else to replace. Dealer and I have replaced 02 sensors and spark plugs , it runs fine for a few weeks then randomly starts up again. Getting really tired of it.

I have K&N typhoon intake with GM stage 1 sensors, ZZP catted DP , Dejon upper charge pipes.

I need this fixed, so annoying.

 

Anybody?!! This is so annoying and my exhaust smells funny too.

 

bump

 

Bumpppppp

 

What's the exhaust smell like? Done an oil change? Checked the throttle body?

 

What's your coolant temp? It sounds like your saying the car runs ok once it is warm but when its cold it runs bad, right? If your coolant temp sensor is reading cold the car will just dump fuel on start up to get it warm. Check that

 

My coolant is normal, about 108 to 112. The funny thing is every time I go to take it in, they say it's asking for more fuel than what is needed , therefore the CEL is going on. Every time they clear the CEL (no maintenance) the problem stops for about a week and a half. The exhaust smells funny when its running bad whether its cold start or warm, but I took it in and they cleared the code till my appointment on WED. No problems and exhaust is fine. even cold start is working again

 

Bad Cat?

 

Shouldn't your coolant reach around 185 degrees when its running? mine sits around 187 after its warmed up and I'm driving.

 

Same! 110 would be cold..

 

Mine did the same thing this past winter, I would start it and it would like go right into limp mode and sound cammed when it was idleing. So would hook up HPT and it was MAF everytime. But like you said after letting the car get warm and driving it, it would be fine.

 

Even if it is the maf that's messed up I think his coolant temp is still really low, no?

 

Sorry long day, yes my coolant is 189 ish sometimes up to 195

 

In his latest post he said it ranges from 189 to 195, which seems to be about normal. My car usually stays right around 194 when driving, but like at stop lights it gets into the 200's...... But yah, like the 108 - 110 tempts seem super low.

 

Mine is doing the same crap.. Ima order a new throttle body and see what that does ill keep you updated.. Give me till Wednesday hopefully ill next day air it then..

 

car is still under warranty, and I am not gonna buy a new TB. let me know how that goes though, it just amazes me that you can clear a code and it runs like new again

 

Ahh, I see that now. Guess thats not the problem then.

 

Actually I pulled my negative battery cable and left it unhook for 2 hours while at work and when I reconnected it all of my codes learned and the cel has yet to come back on.. Runs like **** when it's old but once warm it's fine.. I have replaced the maf sensor, spark plugs, barometric pressure on top of the sc.. So only thing I have not changed is the o2 sensors.. So I am going to try the throttle body under my own suspensions and the lack torque when I'm driving, and the limp mode.. But I will def keep you up to date. If the car is under warranty seems odd they have not corrected the issue..

 

This will be my 5th trip back to the shop. They want it for a few days to see what it does in cold start. I already got into it with the manager abut my car not being fixed. Hopefully tomorrow is the last time this will happen.

 

Good for you man! Let me know what they say please. I hope they do fix it to, thats bull **** you take it in that many times, and they have yet to fix it! Go get em man!

 

Thanks, yeah they told me to leave it for a day or two. here we go driving a damn rental again.

 

Lol, thats alright it is totally worth it if the balt is running like a champ again!

 

What is the second code. The first one is a secondary O2 code and should not have a big effect on the cars drivability.

 

Talk to this guy^
