For the last month or so everytime I come to a stop the engine acts like it wants to stall. The rpm's go from about 500 to 1200rpm a few times then the idle smoothes out. Just wondering if anyone else has had this happen and what it is.

 

My ss/sc did that, and GM has a ECM update for that exact reason.

 

yea GM has a ECM update for that...also if your planning on getting stage 2 soon dont even worry about it if you dont have time to take it in it wont hurt anything and the stage 2 reflash corrects that problem goodluck!

 

it happens to me time after time, ima drop mine off to the dealer sometime this week for service. ill keep you'll updated on what they find out?

 

what year is your car?

 

My 06 had that problem. GM Re-flash fixed it.

 

yeah i think mine was doing that also, but now it doesnt even happen, because i got the stage 2.

 

yea my car is also a 06 must have been a glytch in them...for alot of people it only happens when there A/C is on for some reason but either just get the dealer to reflash it or go Stage 2

 

Its an 06 with Stage 2.

 

mine has stage 2 and does it

 

Does yours do it all the time or just when running the heat or A/C??

 

If you have an aftermarket intake... it more than likeley is the oil from the filter getting on the MAF sensor. I clean mine with electronics cleaner about 2 weeks after I change/clean the filter.

 

i dunno ill go try it tonight when i got to my moms

 

hmm most people who have this problem the stage 2 reflash corrects it i had the same problem and got the stage 2 a week and a half ago and now since its been installed...is it when your A/C is running or without 2?

ballsoutbalt has a good point there is a pretty good chance of that being it because the oil is screwing up the reading from the MAF sensor

let us know when you figure it out

 

It seems like when Im running the A/C or the heater is when it does it

 

yea thats the case with alot of people who have this issue best thing to do is go to the dealer and have them reflash the ECM they have an updated reflash to take care of this

 

thanks I will keep ya updated. Im going to take it in Thursday and see whats up with it

 

If you have a custome tune, don't you loose it when the dealer re-flashes it? and Vise versa?

 

yes...do you have a custom tune? because if you take it to the dealer and they reflash your car it will get rid of the custom tune and you will have the basic stage 2 reflash again...o and make sure if you do take it to the dealer to get it flashed that they know you have stage 2 you dont want them to put the stock tune back on the car that would be bad lol

if you have a custom tune if take it to where you got the tune at and ask them to help you out because there tune they did made this happen...

 

i just got back and it doesnt do the revving thing when the AC is off thx for the advice guys its off to the dealership tomorrow

 

I had it reflashed after I had stage 2 installed due to gas cap, when they reflashed it does that mean I lost my stage 2 program???

 

not necessarily if you still have a 7000 rpm redline you still have the tune and your car wouldnt run properly if at all without the stage 2 reflash

hey man happy to hear that its just when the A/C is on this is what alot of peoples cars are doing also the dealership will take care of it

 

Took the car in yesterday....actually got a call and took it in a day early. They re-flashed it and the problem seems to have gone away. One of the techs said there was an update for the A/C making the idle rough. thanks

 

My 07 does it too. I thought I was not pushing the clutch in all the way at a stop the 1st time it happened. Thanks for the info.

 

mine does it fairly often.. even with the stage 2 kit ... it almost quits some times..i find it will hesitate and jerk a few times when i shift to second gear if i dont step on it
