Another Reduced engine power. Theory - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

kville988 · 05-22-2015, 05:21 PM

So I left work yesterday morning driving completely normal. I was actually going below the speed limit and my traction and stabilitrak lights came on and I got a reduced engine power message. I pulled over, googled this issue and unplugged the throttle body and let the car sit for 5 minutes. Started right back up no problem. Just now AGAIN the same thing happened. And I was driving normal. I called onstar and I got emission codes of course cuz I have headers. The new code read P2138. Everyone I seen says its gas pedal position but the onstar helpline said its
Electronic fuel control system p2138 ....

So in saying that yesterday before work I stopped by a texaco gas station to get gas. I was below 1/4 tank. That's the only thing different before and after this message. I never go to texaco. I always go to shell but the shell station was BUSY and texaco had nobody. So I thought why not. Do Yall think its bad gas or my VTC? I've had the VTC in for 3 months and had no issue with it so I don't think it's the VTC. The gas station I decided to try out I think may be the culprit but I'm not sure so I want you guys to chime in!

My mods: VTC, SW headers, CAI intake. No tune.

It's your vitesse. Throw it in the garbage where it belongs.

Lol. So what about the fuel system? And texaco? Think it's just coincidence? I've had that VTC for 3 months no issues

kville988 · 05-22-2015, 06:15 PM

Anybody else?

tarik1985 · 05-22-2015, 07:11 PM

No problem with the VTC and it's a pretty cool device regardless of other ppls opinions which usually come outta their ass

because how can you say something is worthless if you don't have it and you've never tried it

.. I've heard you're suppossed to get a code if you install headers and don't get a tune. I'm not sure if it's the same code you got.And I also heard of people getting the same reduced power message with a ported throttle body.

krisprz2010camaross · 05-22-2015, 07:15 PM

It is probably the vitesse tc causing that believe me... Take it off for a week and see if it happens again and if not put it back on and see if it happens again. I liked the device when I had it, but reduced power randomly isn't something I want. Maybe if they fix it in the future I will get another. Plus not being to use ALL the modes on a V8 sucks, why have options on it if you can't go higher than 5?

1KillerSS · 05-22-2015, 07:20 PM

Your car ran fine after a few min because it will regardless if you fixed the issue or not. After a few min, the PCM clears itself and you get a new opportunity to set it off again. If you didn't throw a code for a TB or some related issue, then its a little premature to state its your VTC. I don't know why everybody hates on it, I happen to like having control over my throttle settings, the new vets have basically the same feature. As for the culprit, who knows, clear the codes and try new gas. That and get a tune for your mods.

kville988 · 05-22-2015, 07:56 PM

LOL. I WOULD LIKE PEOPLE TO THINK INTO THIS WITH AN OPEN MIND. PRETEND I DONT EVEN HAVE THOSE SMALL 3 MODS. I HAVE A CEL FOR EMISSIONS. IM FINE WITH THAT UNTIL I GET A TUNE, ITS MY HEADERS, NO PROBLEM.

BUT THAT REDUCED POWER IS SOMETHING NEW. HAPPENED TO ME 4 TIMES TODAY SINCE I POSTED THIS THREAD, NOW I HAVENT HAD ANY ISSUES WITH ANYTHING UNTIL I WENT TO A GAS STATION I NEVER GO TO. HOWEVER MY BUDDY HAS A CAMARO AND THE SAME DAY SAID HE WENT TO THE SAME STATION AND HE IS RUNNING FINE AND HE HAS A VTC...BUT HE HAS MORE MODS AND TUNED ALSO.

THESE CODES WERE A PROBLEM FOR OWNERS BEFORE THE VTC WAS INTRODUCED. WHEN I DID A GOOGLE SEARCH IT SEEMS LIKE CAMARO OWNERS BEEN HAVING THIS ISSUE SINCE 2012 MAYBE EVEN EARLIER.

I WILL TAKE ADVICE FROM BOTH. I THINK IM GOING TO BURN OUT ALL THAT GAS, TRY SHELL, AND OCTANE BOOSTER HECK WHY NOT. AND SEE WHAT HAPPENS. IF IT DOES IT AGAIN I WILL DISCONNECT THE VTC AND SEE WHAT HAPPENS. BUT I JUST CANT SEE WHY A MOD WOULD GIVE ME ISSUES NOW WHEN IT DID NOT BEFORE. I WILL KEEP YALL UPDATED TO HOPEFULLY HELP SOMEONE OUT IN THE FUTURE WITH THIS ISSUE.

kville988 · 05-22-2015, 07:56 PM

AND SOMETIMES MY CAPS LOCK GETS STUCK FOR SOME REASON. IM NOT YELLING AT ANYONE LOL

First your engine, now your keyboard! Things are not looking up for you.

CrazyRED · 05-22-2015, 08:31 PM

Why ask a question if you don't want to take the advice?

That being said, I had a VTC and used it for a while with no problem, then I started getting codes and backfiring. It was suggested that I reduce the SP settings to 5 and under. I tried that for a few days on 5, 4, and 3 The codes kept tripping and the backfiring continued. I'm not gonna try anything lower than 3 because what would be the point. SO I took the VTC off, the codes and backfiring went away and haven't come back. My thought is that the VTC is adding voltage that may be damaging vehicle systems such as the gas pedal based on the users that have had to replace pedals that completely burned out. So the VTC may be harming things over time? Then again, maybe it's all coincidence and my car just starting working better on its own after I removed the VTC

It's not gonna hurt your car to take the VTC off for a couple weeks. If that doesn't fix anything put it back on and take it to the dealer and see what they say.
