Shorts to parkas to light jacket weather all within 5 days.
Today, I helped a friend check his wife's SUV brakes. The brakes were good. A little grease and cleaning stopped squeaks. I bought new coil packs at Summit Racing, Arlington. $140 NGK 6 pack over a single $100.18 single Bosch at a shop! No parts stores had a single coil. Using my friend's garage, new plugs and coils went on in about 20 minutes. Only two were tight, all others were kind of loose. #6 looked the worst. The prongs had gunk all over them. #1 was next. The misfire #3 had oil residue. Time for a valve cover gasket and gourmet. The #3 and #5 had different coil packs. The #3 had a replacement Bosch coil. #5 had a NGK coil. The #5 coil part number matches the new set. So three different aged coils. The plugs are 1-6 left to right. The #5 plug was not burned through like the others. It bucked a little at startup then smoothed out. Drove home 20 miles and it ran great. The in gear idle shake is gone! I assume #3 was misfiring enough to cause the shake but not set a code. Well, only once. I'll drive it the next few days and check operation. I wanted to have them installed before shop scanning on Thursday. Hopefully the scan will show what's keeping it awake. Once I know, I'll fix it. Even if I have install an accessory kill switch.
The cap oil sludge is back. It had gone away until now. I guess the cold weather is causing it. Plus the thermostat is stuck open. After the scan on Thursday, the water pump will be replaced.
