MARK VII 5.0

1988 Lincoln Navigator

Engine problem
1988 Lincoln Mark VII V8 Two Wheel Drive Automatic 130.00 miles

My car acts like its being held back and sputters and coughs only if I floor the gas to pass someone. If I drive it normal it seems fine but its really drinking the fuel. Also it takes alot of cranking to start. Any Ideas.

I would like you to perform a few different kinds of fuel pressure test and a volume test, but first replace the fuel filter and test the TPS and see how it goes.

Sounds like it is being starved of fuel.

It may be a plugged exhaust sytem but I really dotn think so, it could be and your extended crank problem could be completely unrelated.
