93 da having problems

[93toonteg]

my DA is jerking while cruising, sometimes i doesn't though. Thinking maybe TPS sensor so if anyone have one for a 93 ls let me know.

Jerking as in surging forward like you're giving it a lot of gas?

no jerking like its falling on its face....i think the TPS sensor is going bad not sure...changed it once and the problem stopped for a while now its back but i thought it might be fuel related but just got it tuned and they said the tune was fine. Not sure what to do...

Hmm the TPS is a definite possibility. I'd check that out first.

How about the MAP sensor? that could also have an effect. the little port in the throttle body that is gets readings from can sometimes be clogged with carbon

just took it for a test drive now its jerking more and more...i have a 70mm throttle body could that have effect on the sensors...it is getting to where it is hard to drive.
