- 1989 4x4 Ranger XLT X-Cab
Hi I have a 1989 4X4 Ranger Extra Cab XLT. It has the 2.9L V6. The truck has 220,000 miles. The Engine was rebuilt at 198,000. It passed smog just fine. I am having trouble with the trucks run ability. The new engine ran fine for 20,000 miles. The problem started after I let it sit for two days. The truck has a very ruff idle, has no power (well less then it had before). Does not miss fire. running so rich the exhaust burns your eyes. Some guy before me put headers on it, but they are the legal ones with the O2 sensor in them. When you take off from a start feels like it is loading up and really doesn’t go anywhere. It does not pass smog. I have replaced the spark plugs, wires, distributor cap (and rotor), coil, throttle position sensor, map sensor, and a few others I don’t know the name of (as a mechanic helped me), O2 sensor, checked the timing (remembering to disconnect the spout connector). I have replaced the ECM (computer), and it still didn’t fix the problem. There are a few exhaust leaks but I don’t think it would cause it to run like this. Does anyone else have any ideas. I am fresh out. The tags are now out of date, because of the smog, so I really need to find out what is wrong. I have tried two different Ford dealerships, who told me they don’t work on trucks that old. There is one Ford dealer that said they would work on it, but I would rather fix it myself and save $100 an hour labor, and 300% markup on parts. PLEASE HELP!
