So a couple of weeks ago I posted a thread about my truck (1995 F-150 5.0) not getting any power to my engine. The engine was sort of sputtering with a random knock, and stepping on it only made it worse. I couldn't get to over 20mph. I've been working on my truck and I've checked out the ICM, replaced distributor cap and rotor, replaced fuel filter, checked out fuel pressure, and I'm getting no codes... and nothing .

So I talked to a couple of guys I met from a local car club and they brought to my attention something I neglected to say in my previous thread... I put 22 in rims on my truck about 2 weeks before my truck started acting up. I didn't think this was a factor since I had the rims for about 6 months before I took them off to take my truck to the mechanic when these problems first showed up. When I got the truck back, I put the rims back on and 2 weeks later... same thing.

So my friends told me that the TORQUE CONVERTER could be messed up and this could cause the engine to run at high rpm's which would lead to overheating and poor engine performance.

The current problem I have now is that for the first 20 min my truck runs fine, except when I step on it... I hear the engine rev up, but it doesn't take off like it used to. After those first 20 min, my truck starts acting up and I'm back to those same old problems. So could it be the torque converter or some sort of transmission problem that's been ruinning my truck?

I'd really appreciate all the help I could get... I'm somewhat of a novice to this and I need my truck for work and school.
And I'd really hate to sacrifice the appearance of my truck... those rims really make it look nice

 

check and see if the cats are plugged. when they plug up they generally make it seem like you have tranny problems, similar to what you are describing, sluggish running, cant get up to speed hardly, etc.

 

will do... thanks

 

i agree. those are all classic cloged cat signs. good luck!

 

When engine speed increases and road speed does not, the indication is slippage. Clogged cats will cause your truck to run poorly but clogged cats, will not cause slippage unless the heat radiated off of them causes the transmission to overheat. Clogged cats get blamed for everything.


You state, when cold, the truck runs fine but the engine revs up but the truck doesn't "take off like it used to". This indicates slippage in your driveline.

Taller wheels and tires will cause your transmission to run hotter, but should cause this problem unless the tranny has some underlying problems.

I'm betting on your transmission.

 

replaced the cats and the truck is working just fine... thanks for the help guys

the truck still isn't taking off like it used to so now i'm probably going to start looking at the transmission for possible problems
