- 96 XLT
I have a '96 XLT (pushrod V-6). With both codes for system lean P0171 & P0174 both banks. Runs excellent. I cleaned the MAF, replaced the driver's side 02 sensor (it was cracked around the top where the wiring harness is attached). Started to run a little better with the new O2. Light came back on in 3 drive cycles. Both codes are still present. Last summer the EGR tube had a vacuum leak where the tube enters the intake manifold. I suspect this is still the problem area. I heard (a rumor from a mechanic friend) that Ford had redesigned the gasket for this (actually a large rubber o-ring). Anyone else hear this or have a part number? Other than a very occasional roughness/stumble at idle, it runs excellent. (107,000 miles). I plan to do a vacuum leak test this week.....
