to check the tps voltage you must not unplug the harness from the tb. you must insert the probe of the tester through the insulation on the blue wire and tap into the wire itself.

Man, take it to a OBDII diagnostic place so at least you can rule out sensors.

the car will run fine then all of a sudden (once a day at most) it will bog like hell when i'm trying to accelerate, feels like im not even giving it any gas. then all of a sudden it freaks out and goes fast, but the car doesnt feel as fast as it should...

Ok so plug the thing into the blue wire, but if the voltage is low or high, what do I do about it? What screw do I adjust?

k it was set at .50 or .52 volts depending on which ground i used... Do you guys think that could cause my car to act funny only 10% of the time? or would it be constant?

how about you reread what the guy told you to do if it isnt on .6 or .61 then put it there with the adjustable screw and do the relearn process..if it fixes it then good but if not then at least you ruled that out..

i tried about 5 different ground spots and got a different reading on each of them (some said .04, and 3 of them said .50 so I went ahead and used those grounds to set it to .61) Now it is doing the same thing, but a little worse... Could drilling the throttlebody have something to do with this? we barely drilled it at all, not even enough to notice the difference.

Any other suggestions? I dont want to take it to a shop because I feel like they are just going to waste time with my car and charge me without fixing anything, i'm not throwing any codes at all and i have done all of the basic stuff already...

It litterally feels like I have water in my gas or something, the car just doesnt know how to act. The seafoam diddnt fix it so i'm assuming its not an injector, i replaced the spark plugs, wires, fuel filter, o2 sensor, etc.

HELP!

already did that - made it slightly worse it seems, but the car has been acting better sometimes than others. The engine also seems to be making a little more noise than normal (sewing machine sound) but its not anything that would cause a red flag in my mind...

the car isnt knocking according to the computer...

drilling the throttle body wouldn't do anything as long as you did the idle relearn procedure. If anything got worse adjusting to .6v, just undo it back to where it was & do the relearn procedure bc it sounds like that isn't your problem afterall. As for the ground, I always use the bolt sticking up on the driver side strut tower.

Other things to try are:

1. change to new NGK tr55 sparkplugs
2. new MSD sparkplug wires
3. change fuel filter
4. complete seafoam in intake, vaccuum lines, and fuel tank
5. make sure your coil packs look good and the main harness on each side is plugged in.
6. check hoses for wear, maybe something is seizing up like the a/c
7. check your fuses
8. take it to a board sponsor and get help


I can't remember how much of this you did, it's been awhile since I read this thread.

Maybe your fuel pump needs to be replaced. I thought the ones on these cars pretty much had to be replaced if you ran out of gas because they would burn up.

how do I test the fuel pump? isnt it expensive to replace? i've done the plugs, wires, fuel filter, and checked connections. Ive also checked the fuses.

How do I test the fuel pump?

where can I buy one, and is there a writeup some where for this? Thank you guys for your help, hope its not the pump because dont those cost like $2k to fix?

If the problem isnt consistant you would think it would be hard to test, but i dunno... maybe i can get a fuel pressure guage constantly running on my a piller or something...
