So i just had my Megan Exhaust system installed today.. everything was fine ..untill tonight.. i was drivin and all of sudden my car goes limp mode..says Engine power reduced.. i could barley get the car to move....so i turned it off..then restarted... it was running fine again but with my engine light on... wtf just happined???

 

did u do anything stunt like before it happened??

 

do u mean.. come on to the gas real good... if so then yes i did...

 

engine detected something bad prolly...mine did the same thing and its never done it again

 

did your engine light stay on after that happined???
something bad??? wtf does that mean??

 

i have no clue lol...but yea i punched mine in first and shifted to 2nd and bam REDUCED MODE.... if it does it again take it to dealer...if not dont worry bout it

 

lol i dont go to dealers... i still need more info on why this happined..do u have the same exhaust system as me???

 

Bump*

 

did you touch the throttle body?

 

i cleaned it last spring.. it was really dirty... so anyways.. i dissconnected the battery and then reconnected it... engine light went out... went for a drive for liek 10 -15 mins... nothing seems wrong now.. who knows it could happin again.. im going to check my throttle body tomorrow when i can see and reclean if i have to..

 

Bump

 

i have megan exhaust. there shouldnt be anything like this directly related to the catback from my experiences. best thing to do would be if it happens again, get an obd2 scanner to check out the cel. without that, your guess is as good as anyones on the internet

 

Make it happen again, find cels. I had a problem like this and its an easy fix if you have the cels I had.

 

I had the Eng Power Reduced and It turned out to be the Accelerator Position Sensor.. What codes is it giving you?

 

YOu said this happened after you added an exhsust?
You may need a tune, or something might not be
hooked up. I left something disconected once after
an oil change and I got that.

Check to see what codes you're getting.

 

This thread is pointless without cel codes!!!

 

Your right,
whats funny is that so many times ive seen threads about CELs and no one gets the codes read and posts them.

If you REALLY want help get the codes read, if you want to go the extra yard, get autozone or adavanced, or use your own scanner and post freeze frame data too.

 

I just bought a Cobalt SS 2007 for my son and we experience a power loss. The "engine power indicator" came on. What could cause that?

 

Yet again.

 

We fixed the OPs problem simply by unplugging the battery for a few mins, his CEL never came back on. Try that
