Car bogging while driving

[SHOtimer]

Either that or just replace the TPS. It is very easy to change and rather cheap.

I think I'll test it first before I buy it. I'm spending more than what I wanted to on this car with no results.

Ok. I tested the theory with the tps unplugged and what I've noticed was that it idled the same but when I reved the engine, it didn't have the same response as it did plugged. It would hesitate to rev but with it plugged and the pedal to the floor, it reved slow but eventually reving high. I hope i'm clear on what i'm trying to describe.

ok, now what codes do you have?

I have codes:

54
63
66

ACT, MAF and TPS faults indicated.

May want to reset the codes and see if they come back after putting some miles on the car. Visual check of the harness for shorts/other problems? Checked your grounds as SHOtimer suggested? I know grounds are a real problem with at least 1st/2nd gen SHOs. Even if they look OK, cleaning and reinstalling can make a difference.

Where are all the gtounds at? I know of one by the cps in between the engine and the wall of the engine bay.

 

[rubydist]

ok, that is about what I expected after you disconnected the tps.

reset the codes and drive for a day or so and check codes again.

 

[SHOstuff]

Ok and I'll post once thats done.
