| Hello, I am trying to get a handle on this tuning issue which has frustrated me forever and I am finally planning to fix it after storing the car for about a year. When starting the car completely cold, idle will be lean ~17:1 (rough), once the car has fully warmed up the idle will be ~14:1(pretty smooth). If I adjust the k-value I can get a proper warm idle at 14.7afr but this will result in an even leaner cold idle (which means progressively worse running). Car runs like crap when it is lean. Kicker is deatschwerks 555cc injectors, I'd like to rule out every possibility before swapping these out. Fuel pressure = perfect
Boost leaks = got them all
MAF = tried multiple and all work
Timing belt = just replaced and no change I'm not going to throw out any of my ideas and I'm looking for fresh insight as I've read about everything there is on the subject. If you solve this for me...I owe you a beer...or 10. And I'll potentially be at ZCON so I may be able to pay up :) Thank you for looking!
