Engine & DrivetrainEngines and Drivetrains can be a major problem for a lot of vehicles. If you are having engine or drivetrain problems, you can post your questions/concerns about the issue. Furthermore, if you are in the process of doing an engine rebuild, post your progress with pictures.
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 The tags are now out of date, because of the smog, so I really need to find out what is wrong.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!

No there is no check engine light on, before and after the new ECM. The truck seems to run better cold. The FPR has been replace. I have not check the fuel pressure, but if it is running rich it is defiantly getting enough fuel, so I have been looking in different areas. Oh, since I bought the truck, it has had exhaust leaks, and ran just fine.

i am also having the rich problem someone told me it could be something to do with the distributor.. and some said clean the map sensor with carb cleaner... that's my only prob and mine has 240,000miles on stock engine..
LOL... If you talk to enough of people, you'll find someone who'll tell you that it might be the air in your tires!
What year and what size engine?
How have you determined that you are running rich?
DId you pull codes? and if so, what were they?

You really should start a thread of your own. It gets confusing trying to fix two different vehicles in the same thread. No one knows who's talking about which truck.

For my sanity, please try to use punctuation and capitalization. I try to help the people who post, but it's impossible to do when the post is indecipherable.
The original OP was in 8/10/2008 I hope it is fixed by now! LOL
Yeah, and that happens a lot. People search the threads, find one like the problem they have, and resurrect the thread with a new post. That's why I recommended to the guy that the start a new thread.
