I have a 98 S70 GLT. I recently had it tuned up with Volvo brand spark plugs and Bosch wires. However, since the tune up I have had a random misfire in cylinder 5 according to the code. What may be causing this?

, you just answered your own question

. On nearly every single occasion that I've seen people use the Bosch wires, they have big problems with misfires. I made this mistake as well when I first bought my car. It got to the point where one of the wires was not making a connection at all and I thought one of the spark plugs was to blame. Sooo... I went to check it out and when I pulled the spark plug cover, one of the wires had completely seperated from the boot. I see people with this problem with Bosch wires on all of the Volvo forums I frequent. I'm not sure what the problem is with the wires (why they seperate), but I just avoid them now. OEM brand Bougicord are the best.
