Hi. Have a problem with a friends 95 5.0 that has me scratching my head.
They have had this problem for a long time and have changed alot of stuff trying to throw parts at it. Ie. Plugs, wires, dizzy cap and Innards. Fuel pump and filter cleaned maf and throttle body. All kinds of stuff.
I went over checked the TPS and MAF both check out to be good.
When the car is in park it opens up to WOT no problems. Engine comes uncorked. Runs smooth no roughness or anything. But when you put it in drive, and go WOT. The motor doesn't load up runs smooth and pulls consistently. But it is only giving it like 1/3 throttle or 1/4 throttle. The engine sounds fine. But it just isnt opening up. It's like it's in a limp mode or something. And with no exaggeration as the 5.0 is pulling now. A smart for two would literally out run it.
I haven't check the stall on the converter or anything yet. Cause I'm kinda at a loss of what it could be. I was figuring from the way it's acting it was going to be the TPS wasn't going to 4.5v but everything checks out.
Any ideas or help would be greatly appreciated.
