that it is possible your fuel injectors are nearly plugged up

if you have been using fuel with ethanol mixed in , i would hate to see what the inside of the rubber fuel lines look like

those rubber hoses are not ethanol tolerant and should be replaced with hoses that are ethanol tolerant

I thought about that, it's a shame that every where you go nowadays has that crap in it, that's close by anyway.

Oh OK, Texaco has been out of business a while where I live the only place I'm aware of that I can buy non ethanol fuel is at Carolina fuels and that place is about 45 minutes from me so not worth the drive.

Well, I changed the plugs and wires and it didn't fix the issue. I also had someone to use a timing light to see if the timing was correct and it was spot on.I redone the compression test and it cam back 140 psi on each cylinder dry and 160 wet. and the truck is still doing it. it's back at another shop right now.

140 dry, is that with the engine warmed up _ still seems a bit low even though it is above what Ron said in post #2 ?


We'll see what the garage says.

Something isn't right, I still think that there is a valve timing problem.
The compression is low because the valves are not timed right to the crank shaft/piston position.

The timing belt/tensioner/sprockets etc. has to be gone over with a fine tooth comb.
It's not staying in time.
There's too much assumption going on here whom ever works on it.

if at last resort

i would dis-connect the catalytic converters and look see inside

the honey comb material maybe almost fully clogged up, preventing flow of exhaust through it

when you did the compression test

did you watch the gauge to see if the pressure dropped off slowly or quickly

sorry I haven't updated the forum, but I've had a lot going on. the compression test figures dropped off slowly, it lossed 5 psi within 30-40 minutes.
