Hey! I'm kinda in a bind. my 86' na is rinning too rich and i cant figure out why. i have tried adjusting it but it wont stop. it really starts to bog down around 3600 rpm when i really get on the throttle for the first few minutes of driving. then it slowly starts to act ok but not up to par. i also have lost some power. i just got my car back after a nightmare of doing an engine swap. someone help!

 

what did you swap the engine with?

its the same as the original, 13b injected N/A from an S4

 

how did you try adjusting it? And because it bogs at 3600ish you think its running rich, or is it hesitation?

 

i run really rich..but i have a turbo...and aftermarket bov vented to atm. it pops all the time



running rich is ok though, just worry if you start to run lean = motor boom

 

the ecu does its fuel calculations with the afm and the 02 sensor...

well, after driving the car around for awhile, you can smell gas from the engine compartment, an it floods out once in a while. so that led me to believe that the car is running too rich. the adjustment that i was turning was the variable resistor by where the stock air box was. i figured that the R was for rich and the L was for lean since they were not on the Right and Left sides (R was on left and L was on right). i really dont know if that is correct though.

 

Hows the idle on it?Is your TPS adjusted properly?

 

dont forget it can leak fuel externally

yup, check the injectors too
