The STRANGEST thing just happened. Started the X to go to lunch. As usual it started with a miss, and tripped the SES. Drove it about 3 miles and parked. While parked I decided to clear the codes. Foxwell said cylinders 3,4 and 5 were at fault. I let it run while I cleared the codes and heres the weird part, the instant the codes cleared so did the miss! Normally I would chalk that up to coincidence but this is the second time in as many days it has happened. WHAT is going on? Why would/could clearing a code rectify a misfiring cylinder?
