Havana, our '95 EVC with 140,000 miles, has some issues that are baffling even the superb mechanics at Independent Auto Works here in Corvallis. I must say that I am of the carburetor?generation?(I've owned three '69 VW buses in my life) and know nothing about injectors.? Thus my descriptions use archaic terminology!? Here are the scenarios and observations of the problems (presumably related):??
1. Minor, but annoying.? Engine is at running temperature and you stop for groceries, viewpoint or gas for 1 to 15 minutes.? When you restart the engine the idle is rough and usually stalls within 30 seconds.? Restart again and pull onto the road- minimal power for about 30-60 seconds, crawl along at 20-30 mph until engine suddenly revs up and away you go.? It is like the choke was on and then it opened up. You just hold the gas pedal in place and wait for it to fix itself.
2. Flat curvy roads, speed limited areas and downhills.? Same symptoms as above if you leave her in Drive and let the RPM's drop below 2500.? The "choking" lasts for 1 to 3 minutes until she roars to life. I can usually prevent this by downshifting to 3rd or 2nd (automatic transmission) and keeping her above 3000 RPM, but what a waste of gas and wear and tear!
She runs like a dream on the open highway/freeway for hours on end [sigh].??
We just?replaced the computer to no?avail although?it?seems to have fixed?the?stalling issue.? Sensors all seem to check out normal. Any thoughts or ideas?? ?
