Listers,
Car has been acting strangely again. I am experiencing a lack of
power/hesitation when I press the accelerator peddle. If I continue to hold
down the pedal there is a popping noise, which I assume is backfiring in th=
e
intake. Any ideas what would cause this power loss/intake backfiring?

The backfiring/power loss happens sporadically and it does not seem to
matter if the car is warm or not. Sometimes if I just keep giving it gas th=
e
RPM's will climb and the car will accelerate properly...

By the way, when the car does this it runs a little rough but maintains a
consistant idle of 875-920 RPM's...

The car does have in the last year: new plugs, cap, rotor, all new
injectors, fuel filter, differntial pressure regulator...

The wires that are in there now are of a unknown age but tested fine out of
the car...

I ran the fault codes and got 4444. All clear...

Car is 88 5000S...

Thanks,
Steve
Michigan
