    not taking a new MAF sensor... I'm not sure on that one... but I just recently cleaned mine with MAF sensor cleaner and it worked great. it only takes a few minutes to do... just pop it out and spray it down, dry it off with some compressed air and re-install. so easy a cave man can do it. and let me tell you mine looked rough. you'll notice a difference immediately. hope this helps you out. I know what it's like I had the same problem you're having a couple weeks ago... turns out I had a bad ignition coil, bad plugs, and needed new plug wires. fixed me right up, and now my 1st gen has tons of power. I had the same symptoms and everything.

    Yeah Ive cleaned my MAF but no my truck wouldn't accept the new one at all and I messed with it for a full day setting and resetting the engine computer. I do have a question about the plug wires you mentioned. On my 2.7 I don't see anything that resembles the traditional looking plug wire that is easily replaceable?? Would love to replace them though if it didn't look like such a job.

    my 95 had the exact same symptoms and they went away after I changed my thermostat. Bogging down when trying to accelerate, it felt like a fuel problem, but only was an issue when the engine was cold and/or it was cold outside. I cleaned my mass airflow sensor but that didn't make any difference. Changed the coolant thermostat and that did the trick.

    the coolant thermostat? That's interesting. Ill look into that sounds like an easy fix. Can anybody back that theory up?

    If anybody is interested I solved my bad accelertation problem after months of digging and searching. It was the O2 sensors and all that needed to be done was to clean them. I just took them out shot them with a little brake cleaner put them back in and reset the engine computer and the improvement was drastic. So if anybody out there has similar problems with there truck I highly recommend this simple fix that only takes about 15 minutes or you can do like I did and search for months fixing things that didn't really need fixing. Anyway thanks for all the help and suggestions.

    Thanx for getting back to us on the solution. Too bad it took so long to focus on the real culprits.
