- 2003 Ford Sport Trac 4wd
I have a 2003 Ford Sport Track with only 120k miles, that I recently purchased. It has a car starter installed and the first thing I noticed, when the car starts and I inadvertently hit the break before putting the key in. I have to start it again. It starts, revs up to about 1500 RPM and then goes right back to 0 and dies. Only way to fix it is either wait for a few minutes to start it again or rev the engine up for about 10 seconds. During that time, it runs very rough. Then it smooths out and runs as expected.
I have also found that the engine occasionally will surge, almost die and then surge again while idling. If I rev the engine up to about 3000 RPM, the engine shakes about every half second, like it is missing.
I have checked the vacuum and changed the elbow hose that commonly fails. I have replaced the spark plugs and checked for the infamous intake gasket leak.
I have cleaned the MAP sensor, the intake valve and replaced the air filter.
There are no error codes. One minute it runs like a top. Then sometimes it will stall and sputter. it will idle as expected, then later idle rough again.
Any have any other suggestions?
