I am having problems with my 96 Ranger that the mechanics are having an issue fixing.

When I drive in 1st, 2nd, or 3rd and let the engine rev up higher than normal sometimes the engine seems to cut out repeatedly. It goes away when I let off the gas and when the problem occurs it never shuts off the engine completely. I don't have a tachometer so I can figure out what RPM I am at, but you can tell by the engine noise that it is getting high.

I sent the truck initially to the mechanic and they noticed ignition sparks along the ignition wires. So I had the spark plugs, wires, and ignition coil replaced. The issue went away for about a week and then came back slowly.

When the issue happens I don't see any of the gauges going low. After the first fix, I started to notice that the check engine light would flicker on each time it was cutting out.

If you drive normal and shift at low to normal RPMs the problem doesn't usually show up. It never happens on the highway in 4th or 5th gear.

This truck is a 4 cylinder and has ~200K miles on it. I want to keep it and I am desperate to find the problem with it. If anyone has had an issue like this please let me know.

I am possibly leaning towards a fuel related problem.

Thanks.
Joe
