Hello Danny,
God....... Just read your story..... I suppose you speak french? The only way I could comment is "J'ai mon (mot d'église...) de voyage"...
Thanks a lot for sharing your experience. I'll do with the other shop in FL. Your car runs OK since the last repair?
As for me, the problem happens when the weather is above 25 degrees... Below 25 degrees outside, it happens but rarely. Only when driving a few hours... Symptom is loss of power when accelerating. Then the 2 messages "engine fault / poor engine performance". After a while (I don't stop driving...) message still there but engine is OK... Sometimes I stop at a gas station and when I strart again, no messages and no loss of power........ ??????? Go figure... Weird, I read a lot and I'm the only one that mention hot weather....
As for the rain (oldmots comment), since I bought the car, only happened once that I drove in the rain... But I'll check that too...
I'll do a good test friday 27th, I'm going to Granby, 5 hours driving. To the "Granby International", (voitures anciennes de Granby).
For car like this, it's very frustrating. Hoping my english is correct...
Thanks again, I'll keep you informed !

Hi Robin,
I do speak french, but will stick to english here for the benefits of the others. Other things I would double check in your case:
- low or poor (old) battery; these ECU are sensitive to low voltage and do stange things after a low peak.
- might want to reset the computers (unplug the battery and short positive and negative wires for 10 sec. Capacitors discharge and ECU are reseted.) In might case, it allowed me to finish my trips before it goes back in « limp mode »
- might be a real physical or mechanical problem too, like an injector doing a bad job when too warm, plugs, or else. Not a pro in that area.
cheers and enjoy you trip to Granby !

Hi Robin,
I had my ECM rebuilt a few times successfully at ASI. Basically every second year I had to rebuilt.
I have to admit that last time wasn't great at all. I suspect changes in their business, but long story made short, I had to return my unit 3 times, every time they said the car was the problem, it took a few months of wait time each time, special parts ordering, paid more than expected, and etc and when plugged in, worked for less than 5 minutes before running on 7 cylinders again. So I had to revert to another plan.
I found off eBay a seller that seems to do a similar job. I was even able to get 2 ECM real fast, even before sending my unit to them for rebuilt - so with the paypal protection, I gave them a try. They were the first to ask me if my car had an EGR valve or not, probably because they didn't had my unit in hands before sending a replacement http://site.ecudoctors.com/images/EC...e-Location.pdf I even paid a bit extra to have a second ECM that I keep in the trunk as a spare, with the proper tools to do the swap roadside if ever I get stuck on the road. Their parts and repairs even carry a 5 year warranty !
I would highly recommend them before ASI today. Both business would ship to canada no problem (I am from Montreal area), simply expect an extra duty and taxes.

Hey thanks again!
All the mechanical possible problems have been checked by my mechanic, but I think the battery is old... I'll surely do the resetting of the computers as you mentioned, and I'll do a visual inspection of the ECU...
Your concern in my situation is a lot appreciated!

Hum, being a french canadian, need a little help.... ! You wrote;

"short positive and negative wires" means connecting them together ???
Thanks!
