00 Jetta manual bucks in all gears
Check engine light is on...says misfire. replaced o2 sensor a few days ago and still have problem. at about 3200-3800 rpm unless you have your foot in the gas the car jerks bad then pushes through it. Its very random, sometimes it does it in all gears, sometimes just 3rd and sometimes not at all. Not sure if its just the spark plug and wires or am i possibly looking at a bigger problem?

Since replacing the o2 sensor, the misfire code is gone but it still reads P0102, P1565 and P1580. We also noticed that the electric air pump has a hose going to the egr valve, but no hose on the place where is actually sucks in air, and we have no idea what it is supposed to be attached to.

VAG Error Code: 16486
EOBD II Error Code: P0102 Fault Location: Mass air flow (MAF) sensor (G70), bank 1 - low input Possible Cause: Probably no serious malfunctions. Loss of power. Intake leak. Air filter blocked. Wiring short to earth. Fuse. Mass air flow (MAF) sensor (G70). Mass Air Flow (MAF) (G70) defective. Possible Solutions: Check wiring and connections. Check / Replace Mass Air Flow (MAF) (G70). Special Notes: In MY 1995-2002 (?) in Europe at VW-diesel-cars G70 had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy / dirty (not easy to clean). You can check functionality by making a log in [01-engine], [meas.blocks-08], group 003 (3e gear, full throttle, from 1700-4000rpm). VAG Error Code: 17973 EOBD II Error Code: P1565 Fault Location: Throttle control unit - lower stop not reached Possible Cause: Throttle valve tight/sticking. Idle speed control (ISC) actuator. VAG Error Code: 17988 EOBD II Error Code: P1580 Fault Location: Throttle motor, bank 1 - circuit malfunction Possible Cause: Malfunction indicator lamp (MIL) Triggered on first occurrence. Wiring. Throttle motor. Special Notes: Maybe caused by low battery if found with 16487 (P0103) As taken from my Free EOBD II Error Codes software - VW TDI forum and Audi TDI forum - myturbodiesel.com |
