I've been running almost 3 weeks on a too lean code have replaced vacuum hoses o2 sensors and such cleaned maf and throttle body any suggestions on what this could be I have an 07 SC stage 3 SS I'm hoping it's a bad batch of gas but not sure thanks in advance.

 

What is the code?

It is probably a MAF and gasket leak.

 

P0171 and I hope it's not a gasket

 

P0171

 

Its going to most likely be an air leak.
Run the motor and spray down you IM and supercharger gaskets with carb cleaner. If it idles up you found your leak.

 

sounds like an air leak throwing things off.

 

I've done all that got nothing I sprayed everything SC IM anything that could possibly leak air and no idle bounce

 

Is your air filter new/not plugged up?

 

Not clogged just recently cleaned

 

What kind of tune do you have? I had the same problem and replaced everything you did and i ended needing a tune

 

What aftermarket parts do you have and what tune do you have?

 

Tbh I'm not sure. I plan on a tune here soon but for what's on there now is beyond me probably just dyno tuned

 

What aftermarket parts are on the car.
What did you change when the code came on?

 

Aftermarket parts are option b 2.8 pulley zzp h/e Megan racing exhaust full 2.5 and aem cai

 

Did you add that stuff and then get the codE?

 

I say you need a tune if you unsure of what tune you even have. And how do you like your Megan racing exhaust? I have one and didn't like the way it sounded after 4,000 rpm...so I cut the muffle off and put on a magnaflow muffler and oh boy it sounds real aggressive.

 

what are your fuel trims ???

 

I'm running 60# injectors and this is the fist code I've seen in 5 months of running stage 3 never had codes before until 3 weeks ago or so and the exhaust is to rice for me lol

 

I had the same problem when my flex started breaking the second time. Air leaks in ahead of the o2 sensor making the car think it is running lean

 

Dude, wtf. You want help but have you checked anything that we have told you?
WHAT TUNE IS ON THE CAR? And no, stage 3 is not an answer. What COMPANY or PERSON put the tune on there?
Help us help you.
