heyhow u all doing? a buddy of mine just bought a 95 passat with a 98 vr6 obd2 in it.no catalytic installed. problem is, that when driving and you give it gas, it starts bogging and the car jolts. just wanna know what i should be checking. hope u can help. thanks
PS: under full throttle, the car almost shuts off. it sat for a few months apparently, so i'll be replacing the fuel filter and doing a tune up on it today.

take out the pre cat 02 sensor and take it for a ride sounds like a bad cat

so did a full tune up, replaced fuel filter, swapped maf with known working one, and still the problem happens. it only really happens at higher rpm's. so if anyone has got ne other tips or ideas please let me know. thanks

Had the car at the mechanic, and when he hooked it up to the computer he was checking the throttle, not sure if you will understand this but he said when the car is in neutral or just idleing the the throttle should be at 10-15 degrees and the car is at 95 degrees (throttle) now when he give it full throttle it falls to 5-10 degrees, do you guys think that it could be a reversed throttle wire?
Thanks for the help

Um, I think that's actually showing you how much is closed, not open.

The higher the % the more the throttle plates are open. The % should gradually increase as you press the accelerator pedal. At one point the throttle % will be at max putting the PCM into a smiler to open loop stated allowing for more fuel to be added and less data to be interpreted by engine sensors. Could be your senors or wiring. Think you can check the resistance of the TPS by manually moving the plates. Check if there have been wire repairs and also look at the color codes. I seen some one on hear posting the readings you should get.

How could we check the wiring? but is it possible the wires are reversed?

replace the crank position sensor I had the same problem in my 95 gti and that took care of it ...

k so found this out. when i unplug the TPS, it idles perfect and runs even better. so i figured it was the sensor. got a replacement and tried it out, but same thing happened. So it's not the sensor but something involved with it, cause with it off it works perfect. so im stumped as to where the problem may lay. is there a specific relay,fuse or anything? thanks in advance
