Question about 1998 Ford Windstar

1 Answer

98 Windstar it really ran the same as before the tune-up. Same guy. It just has a slight up and down on the idle. But, usually it is very good on gas, good mileage. When he first did the tune-up, it guzzled gas double and it is doing it again. The emissions when first taken, showed a too high AND a too low reading. They were even puzzled at the emissions testing. It also showed the idle sensor but that was replaced. I am somewhat knowledgeable in cars, and for some reason this all seems so familiar. Thanks for responding back to me!

I have a 98 gmc sierra 2500 eith a 5.7 L v8 engine. My problem is this: my truck is hard to start, especially when its hot out. I have to floor the gas to get it to start. The acceleration is horrible, so...


The first things I would try would be pulling the vacuum hose off of the fuel pressure regulator and look for presence of fuel,if there is fuel the regulator has failed.Next would be to clean the mass air flow sensor.Also a good tune-up would help fuel mileage as well.

Son let his car run out of gas, and when he filled it this code appeared with rough idle and stalling code 2002


I had a something similar to this happen to a girlfriend of mine. She has a 98 escort and it ran out of gas and the service engine soon light came on after she filled it up. If this is what your talking about check your owners manual. Most of the time if there is really nothing wrong with car you can drive it around ( Generally 20 min in town and 10 on the hwy with 4 idle periods (4 times of the engine being at idle) - do not cut engine off) and the light will go off. The rough idle code most likely happened when the engine ran roughly because. it was running out of gas.

MY 98 FORD WINDSTAR STALLS WHEN I IDLE OR COMING TO A STOP I'VE CHANGED AIR FLOW SENSOR, AIR FILTER, SPARK PLUGS, AND FUEL FILTER ANY IDEAS?


I'd be looking at removing IAC valve, and cleaning it out with throttle body spray cleaner, and checking mounting gasket as well. Usually some success with cleaning it & spray ports it came out of, but if not you may need to replace it.

98 windstar, can't pass emissions


Wow, sounds like your mechanic screwed up. Ran rougher after the tune up is a bad sign. Also, you don't just replace sensors without finding out why they fail. For instance, and EGR code could be a sensor, or it could be the control solenoid, or it could be the EGR valve. Which was it, and what did the mechanic do to determine which it was? I'm willing to bet he threw a part at it based on a code instead of using the code as a starting point to correctly diagnosing the problem. Good luck with that guy. Switch mechanics to a dealer. I know from experience at a Ford dealer for 10 years, that replacing the rear plugs on that car is a pain in the **** and can easily be screwed up.
