First thing is first all i know how to drive it stick shift cars and im having problems with my cobalt ss 2005 well simple its runs fine everytime i drive it like a normal person but when a freaking ricer flys by i downshift and make him look like he is walking you know what i mean
i always peal out even in third gear when i step on it and i hit 6700 rpm i get the damn messege "Eng Pwr Reduced" what the hell is wrong wif it is it my sensor or what please help that crap is driving me nuts im about to change the computer so i dont get that **** no more but im scared to blow something: btw no warranty im over 350 horses

 

Start off by giving us a list of your mods.

You claim to make that much power but you have no way to to monitor things? no interceptor? no OBD2 reader?

 

AEM Cold air intake Eaton M90 2.5 pully short shifter 88.9 MM pistons Hahn racecraft full exhaust (2.5in) 60lbs injectors /w harness kit and other **** i dont remember i cant tell what stage im in i think its 3rd

 

Haha you lost me with that post. You dont have a scan guage or an OBD2 reader? It you get a REP message the ECU will store a code. If you dont have a way to check it, scan gauge/reader, take it to Autozone they will check it and tell you the code for free.

 

you actually have an M90 swap? and i dont know much but im pretty sure you cant put a 2.5 pully on an m90. i wont call bs cuz i dont know enough about the situation but it is fishy

 

That was the same thing i was thinking, but im not going to call BS either. I just dont know.

 

the pully im not sure i gotta go check it out before i know i had a 2.5 but i cant recall if i changed it or not let me check ok

soooooooooooooo sorry i have a 3.0 on my m90 2.5 was on my m62 which im selling

3.0 sorry

 

are you sure you dont have the M62 or did you really do a swap and get the M90 to fit on the balt bc there have been a few guys here who have tried it and they have all failed. iff you have the M62 you can run a 2.5 but i hope you have some major cooling mods and an awsome tune otherwise your engine could go very soon. but you do have pistons so you might be ok
im pretty sure reduced power mode comes on to protect the engine from blowing it self up

EDIT: so you really did the m90 swap you should post up some pics cuz i know ppl would love to see it what kinda boost are you hitting. i only know the basics w/ these cars so i cant be too much help but good luck i hope you get it fixed

 

Find a way to get it scanned and tell us the code. Its hard to help you with so little info.

 

autozone right?

 

Yep. Tell them your check engine light is on and you would like them to check the code for you.

 

camaro man i just sent you a buddy request on aim can u get on man
i really need help

 

they will even give you a print out of what the possible problems can be

TPS, buy it, replace it, done.
