Question about 2002 Ford F150 Regular Cab

1 Answer

2002 F-150 is bumpy when accelarating

I got the service light and put some fuel injector cleaner twice before and then change the sparks and the wiring and cleaned the vaccum pump. When I accelerate it's bumpy jumping like if the vaccum has a leak I checked and nothing wrong there, Also sprayed the system to clean into the intake and still is doing it.

How long since a tune-up? Any applicable trouble codes? The basics if it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.
Crank the starter intermittently so it doesn't overheat. You need spark--fuel--compression, proper amounts at proper time, where applicable, or it won't start.

if you have'nt replaced those spark plugs and wires lately, you need to.and also, lucas fuel treatment, in my personal opinion,is the very best for unclogging fuel lined and injectors.it being below a 1999 model and your check engine light is on, you can have it coderead for free if you're near anautozone or advance automotive parts store. they will code read it and tell you why that check engine lights coming on.hope this helps and thank you for choosing fixya.com

I would check your intake gasket. Get your self ome carb cleaner in a spray form/can and perfrom this test. Run the car and spray the carb cleaner on your intake gasket which is right by your injectors. So pretty nuch spray it at the injector rail and listen fot change in idle, If the idle changes, the intake gasket is torn and you are running lean, because of a vaccum leak. Common problem on your model car. Perform test and let me know what you find.
