took the car to gm to do the stage 2 reflash for idle flucuation but they stage all the engine codes and software was up to date.so everytime i decelerate and push in the clutch the car alomost stalls,the rpms drop to about 500 then flucuates between 750 and 1000. So guys what else could be the problem?. I was thinking maybe the fuel filter??.

 

dude same things been happening to me for a while, but only when i have my a/c on =(

 

Clean your TB and see if that helps.

 

mine happens all the time, ac on or not.

what would cleaning the tb do?.

 

Change your plugs.. my cars rpm's were going up then down, up then down, u might need to re-gap them. let me know if that helps.. im kinda going through the same problem

 

i put new plugs in and gaped them but the problem was happening before i changed plugs.

 

I had the exact same problem until I cleaned out my throttle body. Once I did that, it was like a totally different car. Before you waste your time and money on anything else, clean out your throttle body.

 

GM Stage 2 tune <3

 

dude im sorry to dawg you but for some one with 220whp and 190wtq only running a 14.4.. i would not be trying to get people to listen to me on here.

 

i'll try and clean the tb and see what happens. also the fuel filter. is there any else that could cause this problem?

 

the GM stage 2 tune is **** man.... someone was drinking when they made it. I swear to god it is one hell of a **** tune. I could go on and on about it, if you have hptuners i could give you a baseline on what to use.

 

get some maf sensor cleaner, clean it off, clean the tb, change the plugs.....

If not it's a GM flash issue!

 

he has an injen CAI

im sure its not MAF related, it would take 40,000 miles before it would cause one

 

hmm when i did my stage 2 it ran great i have a 2007 and only had 12 grand now i have almost 16 grand and still running good this is the first ive heard of someone having problems with a stage 2 upgrade without solving it with a quick fix

 

The MAF gets dirty.... I clean mine every 3000 miles

 

well i guess mine needs a cleaning i really dont want problems soo ill check mine out

 

wow, wtf CAI do u have?

BTW

if u want to check out my conservative GM stage 2 tune that GM should use instead of the drunk **** that built it use this as a baseline....

GM Stage2 Dialed

keep in mind timing wasnt touched for safety reasons

Altitude was for 1000 feet above sea level

Piston Protection and COT left enabled so it will run rich under WOT but it will remove alot of the other **** GM thinks is "proper"

go ahead and check it out

 

do you have to register to that site to get that file??

 

shouldnt but if anyone is having problems ill put it on another upload site.


btw any flamers on here, be prepared for logs to show u how conservative my tune is AND the hp i give compared to the Stock s2 tune....

I have logs of both

 

well thanks since i have a stage 2 tune i might look at this file for a baseline

 

-waits for a mod to come in-
