[Thanx Ill check it out.I know what you mean.Ive lived in Detroit,Phoenix area,Boston area have

stayed in New York and LA a few times there is no worst traffic or driving conditions anywhere than L A. :excl:

LA is bad...but Dallas is pretty bad too. I hate going there. The rush hour is more like a crawl hour.

Just because I'm not certain about the lingo, what the heck is a "pumpkin?" And, no smarta$$ remarks about the orange fruit please. )

Pumpkin= "chunk", = rock smasher,= differential, etc. ...to name a few.

I didn't know a Pumpkin was a Fruit..? It could be shutting off for a sec. when you let off the gas. this will cause a big ****.. You might make sure the idle is up at 800 then see if it still does it. Try some good fuelinjection cleaner also..

just a shot in the dark but how about play in the drive shaft slip joint or it just may need to be lubed. plain wheel bearing will do. make sure u mark the shaft so it goes back together in a straight line. also check springs or the spring mounts. they have a habbit of rusting out and breaking. >-

i had the same problem with it jerking when i drove it would shut off when i put it in gear and just wouldn't respond when i stepped i=on the gas i changed my speed sensor, TPS, and my fuel pump now it runs great my fuel pump was going bad that could be something to look at

I changed fuel pump but didnt change filter till a little later cause it was fairly new.Think i could of

damaged fuel pump if there was blockage in filter?And were is the speed sensor?Or TPS? >-

Yep, as are tomatoes, squash and bell peppers believe it or not. I'd just never heard of the diff. housing being referred to as a pumpkin. Makes sense.

I'm anxious to know how this turns out...whether it's a fuel related problem or a drivetrain related problem. My first inclination would be U-joints. I'd replace them all. I had a kind of wobble feel when driving about a year ago. Had a guy look at it and he said it was the drive shaft. He said it was bent and/or out of balance. He was full of sh*t. I replaced the U-joints and whammo, no more problems. (I also went to a buddy and had the drive shaft tested...it was perfectly fine.)

your speed sensor is on the transfercase

your TPS is under the throttle body have someone check your fuel pressure when you turn the car on and check it again while its running thats how i found out what my problem was once i changed my fuel pump my Bronco's been running great good luck

i was thinking have you checked your exhaust manafold gaskets and bolts if there was a leak there it could make a **** cuz the preasure in the cyl. wouldent be balanced just a thought
