Well, I installed the new coil 2 days ago. BTW for those who have to do it, it's a pretty easy job, at least in a non-ABS 2002. I performed the same test and . . . No change. Cylinders 1 and 2 were still about 50 degrees cooler. Then I let her idle for about 10 minutes and cylinder #1 came up to temp with the others. Cylinder #2 never did. So I went for a ride and she runs as well as ever. I noticed something I hadn't felt in a while: while at a stop light, in gear with the clutch in, I couldn't tell the engine was running without looking at the tach. It was that smooth. So, did I condem a good coil? If I notice an increase in gas mileage, I'll say no. A trip to the Springfield Mile over Memorial Day will tell the tale.
Bad choices make great stories
