My Jetta 2001 seems to be ailing a little. Would anyone tell me if there's an underlying cause for the following symptoms?
Quits on me when I come to a moderately quick stop. Other times it revs up and down for a while, I wait for the tachometer to read low and shift into "D" gear quick; sometimes with a big jolt but then it quiets down. Not long ago it would not shift into high gear. I had to drive about 24 km below 85 km/hr to keep the tacho under 3500 rev/min. On the way back, about 2 hrs later, it was alright. It's a pity it, for the odometer only shows about 120K and I like to keep it a little longer, if I could. I seem to have bad luck with garages. They identify the cause, change something, but fail to fix the problem. I still have the "Check" light on after three trials at fixing it.
Is it possible that the Speed sensor needs be changed. Or maybe the ignition harness might be acting . I had it tune, they replaced spark plugs and all hi-tension coils. Most often it works beautifully except for the odd times.
