89 4.0 Stumbling on accel.


Recommended Posts

Normally it won't do it on take-off or 2nd but 2-3 and 3-4 shifts it will stutter, shake and waddle like its a dog passing a pinecone. Oddly though, it won't do it all the time. I'm as confused as hell, I cleared out my airintake blockage, Ive put a new gascap on it, all EVAP lines are good, what is my problem!? argh

 

its an 89 4.0 BA-10 5spd.

my truck was acting up between shifts and it turned out some dumbarse... (coughMEcough) had put the TPS in improperly.

 

check the TPS to make sure its working, it would only do it between shifts and it felt like backfiring.

How would I check the EGR?

 

Its sorta like backfiring. But, now I see, that in-city I don't notice it, but if Ive got more than 1/4 tank, it won't do it.

You may have water or sludge in your gas. That'll do it.
