I have a 96 ranger with the l4. Right before I bought my newish truck last December, it's started miss firing and running really bad. I replaced the spark plug wires, most of the spark plugs, and both coil packs. Didn't help at all. Then I bought my new truck and parked. Fast forward to now. Fired it up, ran REALLY bad. We changed the wiring order from the 96 order to the 99 order and it help a little. But the truck idles from 500rpm (barely running) and randumly jumps up to 2-3000rpm and then back down. Driving it has NO power, rev it and it stays at 2-3000 for quite awhile. Sometimes it randomly dies. REALLY need to get it running quick and cheap. Getting ready to sell my daily driver to find something else and I need something to drive while I hunt for another truck.
Thanks in advance,
Daniel
Does it run better when you first start it up when the engine is cold?
I guess I would start by checking for vacuum leaks - loose air intake, sneak path around the MAF, cracked/missing vacuum lines, etc. It's easy and won't cost you anything but time.
How old is the gas?
Any codes?
What was the condition of the plugs? They might give you some clues.
