Hey all,
I've got a 1993 Ranger 4.0 V6 4x4 that has been giving me some issues. Long story short, it started sputtering and losing power about 6 months ago, so it sat for a while as we can function with just one car in our house, luckily. During this time I changed the oil, spark plugs & wires, and MAF sensor - nothing helped. I finally got sick of looking at it in the driveway and started swapping parts out last week. First was the fuel filter last Monday - thought that did the trick, but it will run normal, then suddenly start misfifing with the CEL on, sputtering and driving with way less power than normal. You can feel it in the throttle response and hear it in the exhaust. A week later (yesterday) I replaced the fuel pump (fun!) and that too seemed to fix it - took it on the highway for a test drive, filled it with premium, and used a can of additive to clean any gunk out. On my way home from the store, it suddenly went back to its old ways on the highway - got off and restarted the truck and viola! Good to go. Didn't drive it to work today, so I just got home to test it and sure enough it is running rough again. I am so frustrated and just want to fix the issue!! Any thoughts? Should I replace the fuel filter again now that there is a new pump? Could it be dirty/clogged fuel injectors? An electrical issue? Like I said, it is intermittent and unpredictable. I will try to pull a code here in a few minutes and post again. Thank you for your help!!
