Ok, I have asked just about everyone I know and noones knows,

Truck starts and runs fine. Drives fine..

Stomp on it for a good bit like offroad or use 4lo any kind of time..

It misses, spits sputters, doesn't run right, till I drive normal for a while of leave it idleing for a while, problem goes away till you run it hard again..

I'm thibk sonething heat related, changed both o2 sensors, spark plugs, tps, idle air control.. nothing

 

You get miss codes, or it just feels like that? Ran any injector cleaner or seafoam thru it lately?

 

Possible cam, or crank sensor.

 

Have you checked to see if your CAT is clogged?

 

Mine does the same thing, do you lose all power? Like have to baby the throttle just to get it moving? I changed my cap and rotor because they were pretty bad so I hope that was it, you should try the same.

 

I'm going to check the crank sensor

I ran seafoam like a couple months ago

Cats gutted, so its not that

Let me know if that cap and rotor fix helps cause yes, I loss everythibg and can't even clumb normal road hills when it does this

 

Ya mine seemed to be a heat related issue. I was running it hard and idling with the a/c on full, the temp gauge never went above 210 but it seemed like something didn't like the heat because turned it off for 8-10 minutes and I was able to climb the hill I was stuck on the bottom of in 4 hi and I couldn't even do it in 4lo, just didn't have the power. Its happened to me twice now so if you figure anything out please post it on here (If we even have the same problem, I'll try to video tape it next time).

 

Oh and I changed my cap and rotor wednesday and the cap was horrible, all the plugs or whatever the cap hits were almost gone. I hope that fixed my problem but I haven't ran it hard recently

 

Yes i try to video tape mine tomorrow, and see if it does it... my temp gauge never goes above like 160 but it just seems heat related..

Funny yhibg is i know my cel works but it never comes on, so I cant even check that

 

Let's keep this one open, maybe someone hasnt seen it with an answer
