I was circuit racing and while I was on my 3rd lap I got a reduced engine power sign!!! I am typing from my iPod right now. The car is on idle and engine sounds good, vaccum is at -20 psi while idle. Noticed that the engine coolant was at 217 but it went Dow back at 190. Please let me know what I can do if anything!!!

 

Push your onstar button and they can tell you what the code is. Then we can tell you where to begin looking.

Need more info....

 

He never said anything about a check engine light.

 

What do you think a power reduced light is?

 

My friend gets it all the time in his Ion. No check engine light follows.

 

If that light is on he will have a code for something

 

No onstar on PUerto Rico and yes, it is followed by a check engine

 

what happened at the exact time the light came on? bad downshift into high rpms?

 

Disconnect the battery for a few minutes and see if it resets itself .

 

Charge piping? What does the car boost to?

 

It does not let me boost under reduced engine power mode. I stop at home before heding to auto zone to see what codes does the ecu has and when I turned the car back on the check engine was on but no reduced power mode!!!! It did not last long thoug before reaching auto zone it went back on. Will post codes as soon as I get them

 

bet you busted that mystery wire, sweetsandman had an issue with it.

 

Although i was not downshifting while it happened I never over reved while i downshifted, each time I did I ended up in the 4.5k to 5.5k range, never went into 6k. I have video of the event but in fear that someone from the dealership might see it and void my warranty. I have raced before with my previous car and never had this issue and frankly I dont plan to go racing on this car again until I have this hole thing down on what happened and why. By the way I almost overtook a Hundai Genesis Coupe (V6 Track version) but the following codes kept me from doing so:

P0091
P0089
P0088

Auto Zone told me they are fuel related issues. Anyone knows what could have happened?

 

p0088- fuel rail pressure too high
p0089-fuel pressure regulator performance
p0091- fuel pressure regulator solenoid 1 control circuit low voltage

 

yup, pm sweetsandman

 

Thanks!! anyone knows why this happened to my car? perhaps something bound to happen at any time? I just wander because I would hate to know that my car is too delicate to be out racing witch would defeat the purpose of having a sports car (even if it is a entry level sports car) I know that if you treat you car badly it will do the same thing to you but I am no newb to circuit racing. I also know that a intermediate racer like me can make mistakes but I can swear I never over reved and that there are a ton of things i still need to learn to even compare myself to a decent racer. I will let you guys know when I release the video from that day so you guys can judge for yourself.

Thanks everyone in advance!!

BTW anyone done any circuit racing on a TC? if so how the car is holding up?

 

This guy's been doing it and taking names: https://www.cobaltss.net/forums/autocross-road-racing-53/serious-note-please-read-171680/

He's a pretty nice guy. I would PM him and ask him. He's pretty knowledgeable too.

 

if you have charge piping, it sounds like the issue that was out there about the piping hitting fuel regulator or whatever it was....

 

Could the charge pipe had hit a fuel regulator component? the charge pipe is the plastic tube the goes across the engine correct??(still figuring out what is what in my car)

 

P0091 is the code I threw. There was a wire that had snapped...took it to dealership and they fixed it in a couple hours under warranty. I popped mine at the track as well ha ha! And they never said anything about the tune I had on it either when they fixed it...Halleen Chevrolet FTW! And driving home from the track in Limp Mode...sucked giant donkey nuts.

 

hey balento that happen to me to and it was that one of the cable of the sensor in the charged air pipe was loose. What part town of PR are you from?

 

yeah it really sucks!! the worst part was that I was about to lap a Genesis Coupe V6 Track, check out the video here and let me know what you guys think

Took the dealer 5 freaking days to service the car and told me they had to replace the fuel regulator

San Juan, we are organizing a Cobalt SS group (13 cars so far!!) if you want more details send a PM
