I have a 1988 Ford E-150, Fuel Injected, V8 5.0L/302cid, with 118K miles. Vehicle runs well but gets only 10 mpg and has a very strong exhaust smell but it is not the "rotten egg" smell. Smells fuel "rich". Vacuum hoses appear to be good.
I'm thinking fuel pressure regulator? If FPR was bad, would that not allow fuel return and "force" (or dump) too much gas to injectors?
This vehicle has two gas tanks with a switch to change tanks but front tank will not supply fuel (probably bad pump) so I run off the rear tank.
Engine idle [u:c266ff9817]seems[/u:c266ff9817] a bit high but I can't be certain.
O2 sensor recently replaced.
Thermostat recently replaced
I have had -- but not recently -- an intermediate "check engine light".
I just purchased this vehicle (very cheap) and need to get this problem under control.
Thanks in advance.
have the same problem?
