Hello forum, thanks for the help in the past - I have an issue that has been on and off for the last few months.
I've searched all over the forum, and other american forums as I am driving a 1992 Canadian Eurovan CL - Automatic Petrol gasoline. Same thing, just different branding.

Either when I am at a red light, or coming from a rolling stop idling- and I add my foot to the gas pedal at a normal pressure, it sometimes just kind of chugs going into gear and dies. It has even died while turning a corner around 20 kms/hour.
Only if I geeeeently apply my foot, it will slowly go into gear with out dying.

I have found countless threads, but not really a straight answer. I have been searching for months! Here is what I have found thus far as possible fixes...

1) Replace ECM relay #30 (spot number 3) and fuel pump relay #80 ( spot number 12 ). I currently have a 167 in spot number 12 instead of the suggested 80, as the van came that way.

Where do I buy these relays? on eBay, I found some aftermarket ones for the 30, but can't find any for the 80. Has anyone here found a good sight to get these from? Or are the eBay ones good?

2) Replace the ECM alltogether. I have found a couple on eBay for around $200 USD, and one 1.5 hours from my city for $100USD.

3) Replace the TPS - Throttle Position Sensor. This might make sense since, lets say I am going 50 kms/hr and I throw my foot down, there is a slight delay until the throttle kicks in. And also regarding it stalling from a stop or a rolling stop.

4) Hall Effect Sender. Don't know much about this one.

5) Fuel pump altogether.

6) Temp sensor, or that little sensor in the ECM that has a vacuum hose coming from it.

7) new Vacuum hoses, replace all

8) New Spark plugs (which I bought, just haven't replaced yet)

I am currently missing 2 feet of pipe that connects the catalytic converter to the muffler, making the bus very loud, but I don;t think this would be the source of my problem, unless somehow it is a pressure issue?



Here are some other threads to read about as well...

It really seems like it could be either one, or a few of the fixes above, just wondering on some advice before I begin ordering parts I do not need.

Thanks!

Bump

Does anyone have a good recommendation for a website to buy relays?

I think I'll start there.

I also forgot to mention, when it stalls while rolling, sometimes I can get the engine back by slamming my foot on the gas pedal.

Sorry don't know much about the petrol engine ones, but just done a quick google, is this an AAC engine? there may may be fault codes to read on the fuel injection system, seems to be quite a lot of information online I would check that out first.

 

[bryanbuss]

Thanks for the reply Bruce!

What does AAC mean?

Some more searching, found this thread
http://www.vwt4forum.co.uk/archive/index.php/t-184205.html

There is a VW shop in town I could take it to, and I am sure they could read the fault codes, thanks for the tip!
Could be that sensor in the ECU, so possibly replacing the vacuum hoses could fix it.

I guess really, there are so many possible issues, has anyone else come across this problem?

AAC would be the engine code.

As you seem to be proposing the poke and hope route then rather than starting with relays, I'd go for the service/cheaper items first and change the plugs then pipes. seems some of the small air pipes have a reputation for blocking with dirt as well as the rubber aging and cracking so no longer effective for any vacuum. also check that the pipes between air filter and inlet manifold are all properly connected and not leaking.

I'd add checking the ISV Idle Stabalisation Valve to your list.

What happens if its in neutral and you pick up the revs then remove your foot from the pedal, with a warm engine it ought to drop to about 1000-1200 revs hesitate and then settle slowly to tickover.
