Ok, so I have been having some issues with the 95 explorer sport that i recently bought.
First I bought it being told it needed a starter and a flexplate. Bought both used, had the starter tested so I knew it was good before putting it in. Finally got the old one removed and it was siezed up, and tested bad. Checked the flex plate and it looked good. no grind marks, turned fine with no obvious breaks in it. So i decided not to worry about it. New(used) starter went it, and I got it to turn over the motor when I jumped the terminals, but it would not start the truck. I knew fuel was good cause I had replaced the fuel pump when the PO had it. Checked relay and fuses anyways. All good.
So upon reading another couple threads, i read that some people have had issues with the Crank Position Sensor when it would turn over but not fire. So I tapped on that, as well as re-seated most of the sensor connections on the top of the motor.
The one thing I didn't do was replace the one Spark plug wire that looked corroded. Oh, and I also changed the oil, but found no indication of metal in it. And with the face that the motor turned over without issue or noise, leads me to believe that it is fine.
Now, After havin done all this, and charging the battery, I finally got to test it. It started, and maintained running, but it ran really rough and loud, almost sounding like a spun bearing, but not quite, and it stayed running for about 3-5 min without help (more throttle) and it didn't sieze up at all, so I figured that it probably isn't a spun bearing.
So what could it be? My guess would be a misfire caused by the plug wire, which is now replaced, but can't test due to the starter not engaging again. other guess would be the flexplate let go, but would that cause it to run rough and a vibration? The truck was not driven, just sat there and idled.
Any help or insight is greatly appretiated.
