and I didn't even tune the thing up properly. i know it could use a new cap and rotor and maybe even wires (the guy i bought from said that had just been done but he was full of BS, he tried to sell the thing as a 4-Matic, not, so i know it needs a good tune eventually)..anyway, i suggest trying the old plug route first and see what happens. it's the cheapest way to go and if you need to keep going at least you can eliminate the plugs and proceed from there....good luck....
