i have a 97 integra gsr with a drag gen 3 turbo. it has a crane ignition also. i am having a problem with the car when it goes over a large bump, or gets jolted hard. the fuel concentration seems to be getting out of whack. before the car his a bump it runs fine and the a/f guages goes from lean to rich, up and down, like it should. after it hits the bump it stays at rich when i have my foot on the gas, and as soon as i take it off a little it goes to stoich, there is no inbetween. the car also backfires alot when its like this. if i turn the car off then turn it back on everything goes back to normal. i was thinking maybe it was some sort of sensor or electrical piece but im not sure. any info is appreciated. thanks.

 

Have you tried posting this in the Forced Induction forum?

 

It sounds like you're being switched into open loop.

Maybe there's a short in the TPS, or if you have a VAFC, maybe there's a short in the wiring there.

 

i put it in the forced induction forum, but i think they removed it, thank you.

so you think i should buy a tps sensor? or the wiring might be lose?

 

i have a fields vtec/fuel controller, but i turn it off most of the time because it eats my gas, but it still gets messed up whether its on or off.
