Engine Performance problem
1999 Volkswagen Jetta 4 cyl Front Wheel Drive Manual 140000 miles
My 1999 VW Jetta, Stalls out in acceleration, mainly from 1-2K RPM. And will fall flat. And it is getting worse as it goes. When up to temp, It is not "as" bad.
Things I have fixed already: Plugs, Wires, Fuel Filter, Air Filter. I have done the Basic trouble shooting.
The code reader says Vacuum Leak but the Vacuum tester showed it was fine.
After doing some research it points to 3 things.
O2 sensor, Fuel Pressure regulator, or MAF sensor (replaced 1 year ago) They all range in the 50-100+$ range. I don't have the $$ to throw parts at it.
Do you know of any thing that would be the main problem? If I had to buy 1 part. What one would you do?
have the same problem?
