highway trouble

[96chev]

when I'm on the highway the engine or Trans jerks on me. sometimes hard sometimes not so hard. Not sure what it is. Does it about 65mph. Ill have my foot steady on the gas not accelerating. Plz help!!

I am assuming from your username that it is a 96 Hoe? 2x4 or 4x4? When was the last time the tranny was serviced? Flushed and filters changed?

I just got my hoe a week ago. i am fixing it slowly. It is 4x4 and the guy i got it told me he had the engine rebuilt. And a new transmission. That's all know about it. It has 249000 miles on the body. The engine was throwing a mass air flow code and a cam sensor code as well fixed both of them and there still coming up. Abs light is on too but i don't think that's making it jump or jerk like that.

Could be a worn valvebody in the trans. Could be the TCC solenoid, could be numerous other things. Shure it isnt a missfire? Plugs/Cap/Rotor/Wires been changed? How were the Cam sensor and MAF sensor codes taken care of?

 

[96chev]

i pulled the parts from my job, i work at a salvage yard, i changed the mass air flow sensor and the cam sensor, but they were used parts. the cap had a little build up on it but i tried to scrape it off, have not done a tune up yet. what do you suggest i do first?????:help:

 

[lesterl]

I would do plugs, wires, cap, and rotor (all new of course) And I prefer the oem cap and rotor if possible....

OK I GOT IT, IT WAS JERKING ON ME BECAUSE OF A CRACKED VAC LINE, THAT WHY IT WAS ALSO IDLING FUNNY ON ME AS WELL. THANK YOU FELLAS. :waytogo:
