ok now im stumped i just pulled the codes and i get code 32
32. Fault in barometric pressure sensor circuit OR Fault in exhaust gas recirculation valve diagnostic switch OR Fault in electronic vacuum regulator valve
well i know that set cause since day 1 the egr valve hasnt worked and it also no longer on the car
the car still idles and runs dead lean,i even tried tipping in the tps as far as i could to try to richen the motor up but that didnt work.
just to dbl check the o2/af gauge i pulled one plug wire so it would have a dead miss,and sure enough the af/lights started to climb a lil bit.
figure tom ill dbl check fp at work incase the fpr went bad or the fuel filter is cloged.
but if its not that i cant think of anything else to check
btw the lowest i can set my boost preasure to is 3 psi and even at that low boost its still lean.that car was running fine a day ago had it out with 9 psi and it ran perfect

 

Are you using a wideband O2 or just one of those guages that just show rich/lean? I would try using tunerpro or some such software, getting an ALDL cable and seeing what this thing is really doing on BLM's and such.

 

im using reg o2 and gauge(ive had the car checked with a wideband against my gauge so i know were it should be running on my gauge) for now since ist all i have,i know for a fact the car is lean though,its running hot,plugs are white,cars down on power,etc, i have the laptop and all for data loging, i just dont have an aldl cable yet.i should have mentions my original ecm had fried a few days ago so its been replaced(car wouldnt run with the other one)this problem just developed today.i dont think its the new ecm though atleats its not acting liek it.

 

if you're using a regular o2 sensor and guage (autometer, ect) they only read wot, there's no way you can know at idle if you're running lean, and even wot isn't awesomely accurate, but close.. BUT i'd check your fuel filter, and then the lines, maybe a line is rotting and leaking a bit, losing some of the pressure.

 

fp is good 45-50#'s at idle and all of a sudden the car started running right again,so im really leaning twards a faulty junkyard ecm,so im gonna step up and switch over to a speed density system,which will mak eit easier anyway with the twin turbos no more ugly ypipe to hook up the maf sensor.
