ok here is what i just found out for the hell of it i unplugged my MAF and started the car and it actually idleing around 1000 rpms and did that for a while untill i shut it off however throttle response still bad.....BUT when i plugged the MAF in while it was running it would instintly die ............but while the car was running i was able to set the timing (w a timing light) and actually got a good reading 15 degrea before TDC and also adjusted the TPS to .45 volts althou when i unplugged AAC and tried to adjust the idle scew nothing changed no idle up or down.......does this sound like a bad MAF to anyone? thanks for reading
