Barrie1: I have no idea how old the spark plug wires are. I had the
spark plugs changed about this time last year...is that the same? I'll tell my mechanic about the spark plug wires and the air filter when I get the oil changed on friday.
Ok, ArticSteve, my mileage is about 145,000 kms. I have automatic transmission.
"Personally, I don't think your problem is associated with water in the fuel. Its normal to hope for a simple cause."
I don't know what else it would be, b/c as I said earlier, it never does anything for my mechanic. And since I explained it to my co-worker (the one who worked in a garage)
and my mechanic, they both said to add methyl hydrate (mechanic), or gasline antifreeze (co-worker).
Is Ethanol in Petro Canada gas? We only have 3 gas stations locally (small small town, where you have to drive at least 10 miles to get gas)...Esso (which is the one I have been using 99% of the time), Petro Canada, or Co-op. I was told by my co-worker that since he started using Esso gas, he's had the same problem I've had. So I'm kind of wary of sticking with Esso for right now. I always thought Petro Canada gas was one of the best gasses out there.....
Is Isoproply alcohol the same as gas line antifreeze? (Can you tell I don't know what I'm doing??

)
My car has been doing this since about the end of November/early December when it started getting cold here in MB. Since we've had such a stupid winter (no winter to speak of really, temperature wise), it's been doing it since about then, regardless of the temperature. It can be +5C or -20C and it still does it. I have been letting it warm up for about 20 min to half an hour each night for about the past week (b/c at night time it's been getting to about -20C, give or take a few degrees). It's usually good for about 5 miles, then it starts to jerk. Usually does it at higher speeds, from about 90 kms, to 110 kms. Since I rarely go slower (I do a lot of highway travelling), I don't notice it when I'm driving in town. And if I'm going up and down hills, it seems to do it then too. Even little hills.
Hope that helps you guys out.
