Your problem may be as simple as changing the catalic converter. So you are cruising down, with 70, then a broken piece clogs the exhaust in you muffler, and then when you turn your engine off everything returns to normal. Is that it? I had something like that before. The catalic converter sometimes breaks in little pieces, and clogs the muffler. One way to know that your exhaust is clogged is that your RPM drops down much slower than it did before from 5-6000 to 1000

Russ,
Can you post what the temp gauge indicates before and after you experience the power loss? I'm guessing here, but it sounds like as the EV warms up, you're losing the benefit of the enrichment injector so you fault may be in the fuel injection system - the normal operating mode has a problem somewhere.

Do you have any ideas?
By the way, I have Goodyear Regattas on the van. My complaint is the tire model only rated for 1,400 lbs instead of 1,519 for the G64.
Thanks,

I believe the enrichment injector (single injector on the intake manifold with blue connector) only fires for a few seconds. ?It's out of the equation once the engine's running (unless its fault is that it's open all the time, in which case you'd get too cool running, and bad mileage).

I had a 93 evc and it did the same thing . The dealer couldn't fix it as he said he had to see it happen . I gave it to them for a week and still no help as i drove it away from the shop it happened again ,I was so disgusted I started looking myself even tho it may have voided the warranty.I think the problem left after i replaced the o2 sensor.I learned to turn the switch off and on while running down the road after awhile it would clear up.There was bulletine issued by vw that said it could be the contact on the ayr folw meter that was momentarily losing comtact.

I agree that's a smart place to check (forget the enrichment stuff). ?When the conveter is cold try tapping it with a rubber mallet and listen for loose pieces. ?You can also hear loose pieces at idle in certain situations.

It's certainly true that a fouled and/or poorly connecte OXS sensor will cause a variety of problems. ??I disconnected and re-connected mine once and immediately could not smoothly rev the engine (it stumbled badly under load in the vicinity of 3000 rpm). ?The problem DID go away with the OXS sensor disconnected, so that's an easy and quick test.

I recently had similiar power loss
problems.? My '93 Eurovan would loose power and not rev past 3000
rpm.? I thought immediately that it was an oxygen sensor problem.?
Unpluging the oxygen sensor seemed to help, but only for a few minutes of
driving.? I limped it over to my friends garage and he hooked it up to the
OBD computer and it came up with a bad OXS and bad coolant temp sensor.?
The OXS had been replaced on the van previously and the code might not of been
reset so on Friday I took the cheap route and replaced the $11 coolant
sensor.? This morning (Monday) I was back at the dealer buying the $170 OXS
.? It didn't seem to fix the problem either.
?
It ends up the cat is toast.? It has a shattered
core.? I cut the exhaust and undid one pipe connection and dumped it out
this morning.? After putting everything back together, it runs great.?
The exhaust rattle I thought I had is gone too.? Turns out it was the cat
pieces rattling around.
?
Has anyone on the list priced Catalytic Converters
lately?

My cat. price was about $300 using a aftermarket and $500 using a VW part. Justin

An engine of the 90's with everything working BUT the cat will handily pass emissions tailpipe testing, and obviously a gutted cat will pass the visual inspection. ?A fair question to ask is how much environmental damage is done producing a new cat versus how much environmental damage is done driving around with a gutted one? ?There is no free lunch. ?My guess is the best thing you can do for the environment is make sure your OXS sensor is working correctly (my guess is that if your OXS sensor is faulty and slips into its default-to-rich mode, you'll be doing lots more eco-damage than running with no cat at all).
