I got two coils replaced under warranty, bought 6, bought all new plugs (Motorcraft plats), MAF sensor cleaner and TB cleaner, and Lucas fuel treatment.
I found all kinds of issues during my work today.
1) MAF sensor wire was literally covered in oil and grime. I had never treated this part before. A few bursts of CRC MAF cleaner and the wire and red sensor was bright and clean. I also blew out my K&N panel with compressed air and saw no signs of excessive filter oil.
2) TB was pretty bad. (pic 1) Cleaned thoroughly with CRC TB cleaner
3) A few of the plugs were baked pretty good, and had a good bit of oil at the threads but not on the electrode or ceramic insulator (pic 2). No oil or moisture in wells at all (thank god). Btw I posted this in the other thread but the VCG's were replaced 18 months ago. The new gaskets are doing their job.
1) All the old plugs had a .048" to .054" gap (pic 3). New plugs were gapped properly at .041"
3) Clip/connectors on two of the coils were broke. They were still seated but the clicky thing wasn't engaging. When reconnecting the coil connectors, they all got a good smear of grey RTV across the clips to hold them together securely.
After I got everything put back together I drove her for about 20 miles, making sure to get shift points learned without any WOT. I will probably try to take her easy for another 60 miles or so, but so far the drive is fine.
