SOURCE: idles rough ,loss of power

I had this same problem on mt 2004 jetta. It had 85,000 miles on it. one day it bagan to idle rough but seemed fine when at higher sppeds/rpms. after a weekm I took it to the dealership and it turned out that a few of the coils/springs were shot. they also replaced my spark plugs, costing me about $550 total. But the car runs great again.

SOURCE: 1990 dodge 360. Runs fine. unpredictable backfire

You want to check your timing for accuracy and then check all plug wires for burned or cracked ends. Also check the single coil tower where the coilwire connects for very small cracks. Then check the inside of the disrtibutor cap for the same small cracks. Throughout this process I'm certain you'll find the culprit. Thanks, Dana

probably the throttle position sensor,but also could have jumped time.i would take the T.P.S. out and check the resistance,i am not sure what the correct resistance is for that model but you can find out at the parts store.

Engine start but continue to backfie


A backfire is a sight of a plug firing at the wrong time. Have you had the plug wires off recently? This would easily explain your problem, if not.....I would be checking that the engine is in time.

I have a 1994 mercury sable station wagon. while sitting at a stop light the engine died. when we finally got it restarted it began to back fire alot. Then all of a sudden it began working fine and ran...


A solution is hard to give with out looking at and doing some testing but advise and help i can do, this sounds like a lack of fuel pressure, it died out and was hard to restart and backfiring from loss of fuel, this sounds to me like a fuel pump that is on the way out,

The first thing would be to have a fuel pressure gauge connected to fuel rail so that you can watch the pressure as you drive and see if you loose pressure when car begins to die out or back fire. good day

Running rough-1987 Ford Ranger 2.3 L 4 cyl. Had been running very smoothly until 2 weeks ago when it began backfiring and running rough, especially at low speeds, without my having made any adjustmen


If your car has a mas air flow sensor (usualy located right aroung air filter or in air passage after the air filter) check and clean the sensor. This looks like a small spring on the end of 2 wires. BE CAREFUL not to damage the sensor. I have seen where the sensor gets dirty over time and this can cause a rough idle.
