Question about 1998 Volkswagen Jetta
2.0 L replaced fuel fltr. plugs,still rough getting worse ???????????
Getting worse? Are you having to top up oil regularly? (oil over-filled and damaged hydraulic lifters / Piston rings failed / valve-stem seals decayed) Is the oil-cap gungy and yellow/brown froth? (Head gasket failed / head cracked / piston chamber cracked) If thats all ok, then its possible you have an air leak: Does car cut out when you slow down and stop? Does it hesitate when you accellerate from standstill in normal driving? Can you hear any whistling from the engine? Check for air leaks between the air flow meter to the head. I cant remember if this model has a throttle position sensor, but that might be dirty/faulty. Try spraying an electrical contact cleaner (not WD40. You can get contact cleaner from Maplin etc) into the throttle body (DO NOT SPRAY ANYTHING INTO THE AIR FLOW METER!). Finally, check the HT leads and the Coil pack. Good luck
