plugs not working. Help.? My car is a 94 buick skylark with 3.1 liter engine. i changed the spark plugs and when i was done i started it up and it smelled like strong exhaust and slightly wierd idle. So i checked the wires and they seem fine. Then i took plug boot out of 2 of the plugs on distributor and no spark. there was spark on every other plug. on the distributor the two in question are next to each other in the middle numbered 3 and 6 of the firing order. i hope i am explaining this right. I have a book to the car but cant make a whole lot of sense out of the dynamics of the distributor and the plugs...what am i missing here
