i totally agree

 

Probably need to grease your muffler bearings and replace the canuter valve. Sometimes when it sticks it causes bank 1 fuel trim issues.

 

front o2 sensor.

run leaded gas much?

 

Why fuel trim issue bank 1?

Because racecar.

 

If any of you are on the fence about getting tires, TR's stock say's "less than 7" for R-S3's. I would call first thing this morning. Who knows how long it will be til they get more in...

 

Chu, weren't you just saying about how long your o2 sensor has lasted?

 

Why spend $50 to get one hoosier tire shipped from TireRack.
Because race car.

 

Why replace only one tire?

Because racecar has no abs.

 

D'oh! !!!!

Btw, im replacing 2 tires but have one free tire certificate from hoosier. One tire shipped direct from hoosier is $18.

 

No. I don't spike my tank like you guys do. Just came on suddenly on my home yesterday.

There were 10 when I placed my order.

I did mention that, about my Autozone sensor being in there for over 30k. But I'm not so sure it's the sensor that has gone bad. The little bit of research I've done doesn't suggest it.

 

^ What does it suggest?

 

Vacuum leak...possible leak on line going to the fpr is what I'm thinking.

 

Here are some potentials, this is from a DSM manual however.

Potential causes for the P0170 code are:

Volume air flow sensor output frequency
Injector
Fuel pressure
Intake air leaks
Engine coolant temperature sensor
Intake air temperature sensor
Barometric pressure sensor
o2 sensor
Exhaust manifold cracks

 

Just when I sell my wideband and boost gauge, thsi crap happens!

 

log your fuel trims in evoscan and see if the STFT is +/-15 (or +/-25), or basically maxed out. if thats the case then its your o2 sensor. I've gotten that code about half a dozen times and its always been the front o2 for me... just sayin.
