Another 171 Error Code Problem
I recently bought a 1995 Ford Ranger XLT Extra Cab pickup truck 4.0L V6 AT PS PW PDL – 2 - RWD
odometer: 194000
It does have an OBII connection which I monitor with my phone via WIFI.While driving, I intermittently get error code 171 Bank One Lean. Recently I noticed that if I park nose down at a sever angle (25-deg) and then rev-up the engine, I will immediately get an error 171. The truck run great with no other problem, just the check engine light and error code.Work already done to try to correct the problem.
NEW ITEMS:
FUEL PUMP
FUEL FILTER
AIR FILTER
EGR VALVE
IDLE AIR CONTROL VALVE
MAF
INTAKE MANIFOLD GASKETSA
LL THREE O2 SENSORS
PLUGS, WIRES
Recent garage work included the Smoke Test, which did not find a problem.
With all these items replace, what could be the root of the problem?
Thanks for your inputs.
