When I run my vehicle through a car wash the "check engine light" comes on. The engine runs fine for the first 3 minutes or so, then will start to run rough, then the light comes on.
I have had the codes read:
P0171, P0174 "both banks running lean".
Here is what I have done so far:
checked vacuum - normal and strong, consistent
replaced MAF, then cleaned the new MAF
replaced plug wires
replaced fuel filter
The vehicle does not have any performance problems outside of the car wash.
have the same problem?
