I have i/e/h test pipe. msd 6al ignition B&M fpr... My car is running so damn lean.. I checked the plugs the things are glowing white!!! I tried turning up the fuel pressure, retarding the timing.. Still is running very lean.. Can anyone give me an idea of waht could be wrong?? I did a search but none of the info i found helped me.. Any info would be greatly appreciated..
Sorry its a 2000 GSR

V-AFC, but if your driving an R that's really strange cuz they run rich as hell stock. I hope your using 93+ octane. Actually I just realized I'm in the integra forum not the type-R, so I'll ask what model are you driving?

usually its the primary 02 sensor that makes the call to the ecu to control a rich/lean condition..
Out of all the problems to diagnose, these running conditions are the worst and most difficult because of all the variables involved, If you have a scan tool to read the all sensor values at normal operating temp then it would be a plus..
Sensors/componenets that would cause this condition..

Fuel Quality
Fuel pressure
Fuel Injectors
Fuel pressure regulator
02 sensor(s)
Valve clearance
Map Sensor
Exhaust leaks
Intake air or coolant temp sensors
TPS sensor
Baro sensor

What a nightmare!

the whole idea here is to determine fuel/air mixture when its called upon, problem being that something isnt making the right calculation when its called upon.. I mention alot of variables here, but it is mostly one faulty component causing the condition due to a slow response rate, usually an 02 sensor.. in most cases it would be the primary 02 makes all the noise and the secondary determines N0x gases from the cat back.. if you had a scan tool you would be able to see how much more response is given from the primary 02 sensor compared to the secondary 02, the primary is the one that usually sends the wrong info, but again.. there is alot of variables here...GL

 

Thanks for all the info.. I will check out al these variables.. My good friend works for acura so I will have him hook it up to the PGM tester.. Thanks agin... Anyone else fellfree to respond..
