Thanks for the input!

Every 3-4000 miles depending on how much driving I do during a single week (can range from 100 miles to over 1000). Again, used car syndrome, but I know at least the car's been babied for the last 25000 miles or so :) > 3: Wrong spark plugs? Might want to check and make sure the correct ones > are fitted. That's a good point. When I bought the car I didn't know that the previous owner had put platinum spark plugs in it. I only found out at 70,000 miles when my ignition module blew out earlier this year. Nice $300 part broken by $11 worth of spark plugs!!! I've run the stock Bosch ever since then and plan to do so until the car withers to dust. I think your number 3 is probably the correct one; I don't know how long the previous owner ran platinums, but I've already figured the previous owner was an a**hole! According to the dealership I bought it from the car had never even been scratched as far as damage... but after a recent parking lot fender bender (while I was half a mile away from the car), the shop discovered frame damage that predated me buying the car. It also had an aftermarket bumper instead of a Saab one and one of the headlight mountings was cracked where you couldn't see it without removing the bumper. If I ever find the previous owner, I think I'll shoot him/her :)) -- Gavin Haslett thumper_svxnopsamo.com http://home.earthlink.net/~hackrat "Ahhhh... Mountain Dew... nectar of the geeks!"
