cylinder 3 misfire
hello, I have a 99 v70 glt 172000 miles. Accelerating on the highway last night, I noticed a nasty car smell that continued untill I got home. It wasn't until I slowed down at the driveway that I noticed the vibration in the steering wheel. I hooked a computer to the obd and got p0303 cylinder3 misfire code. So i pulled the ignition coil off cylinder 3 and inspected for cracks, none. I pulled the spark plug and it looked fine, i sanded it anyway. put it back in, and swapped ignition coil with cylinder 2. Then i cleared the code. I started the car and let it idle for 15 minutes, came back out and the cel was on again. pulled the same code p0303 cylinder 3 misfire. i swapped the spark plug with cylinder 2. same code. any ideas where to go from here? wired look fine. any help is appreciated. thanks

thanks for the replies. I havent been able to mess with it, and I'll be busy for a while. The car is goin to the garage friday, and Ill have them check the compression. Gdog I did swap the spark plugs between 2 and 3 and the misfire remained in cylinder 3-or so my code reader said it did.
