Question about 1990 Ford Ranger SuperCab

1 Answer

1990 ford ranger 2.3L running rough at idle and while driving

While I was driving my ranger it started running real rough. It set for about 2-3 hrs and started ok, then ran rough, then all of a sudden started running fine again. Went to drive it about 10hrs later it ran fine for about 15-20mins then started running rough again. Parked it and it idled really rough. checked for spark on one of the coil packs and 2 of the wires had spark and 2 didn't. Is this normal? Since this 4 cylinder has 8 plug wires,I wasn't able to get to the other coil pack to check it. Does anyone have any idea what could be causing this or what the solution is?

You state you changed plugs and wires - Do distributor cap & rotor? If not you should then set timing. That should cure hesitation (might change fuel filter also and run good fuel system cleaner through it)
Prob 2 - sounds like a u-joint or possible brake pad/rotor issue. Does the squeal only happen in mornings when cold? Sometimes after sitting overnight, rotors get condensation and when backing out they'll squeal/grind. Somethings to look at...

My 1990 ford ranger running rough obvious vacuum leak idles 7oo rpm and while in gear with the break on truck nearly dies but idles ok but not great in park


Use a length of rubber hose to listen around for the leak.
Or use some brakeclean or starting fluid to see where the leak is by it reving up. (stay away from the alternator).
Pinch off any vacuum hoses, one at a time, looking for one that makes a difference.
