I have a 1996 ford E-150 it has a 351, 5.8 engine with 288,000 miles.
The van throws a banks 1 and 2 lean code, the pcv valve is good, the maf sensor has just been cleaned, and i just spent over $500 on getting two new cats installed beacuse the others were messed up, the o2 sensors were replaced, and the egr valve was replaced. The crazy thing is now it seems like it runs worse than before.
Im really dont wont to give up the van but its getting pretty damn expensive.
Does anybody have any ideas on what could be wrong?
thanks in advance,
