[QUOTE="03'Darin, post: 1247593, member: 21082"] Drove the truck quite a bit last night. Plugs made no improvement at all and may have made it slightly worse. Hotline responded again. When they originally told us to monitor the torque converter pids looking for slippage they say anything over 100 rpms of slippage wasn't acceptable. That was apparently a typo because they've now said 10 rpms of slippage. So we need to go check that again. If over 10 rpms of slippage they want us to replace the torque converter. If 10 or less they want us to monitor the down stream cat 02 sensors. Tech doesn't think the 02 monitoring will help because those 02's respond to slow. Hopefully we'll get time today to do more data logging[COLOR="Red"] [SIZE=1]---------- Post added at 10:40 AM ---------- Previous post was at 10:37 AM ----------[/SIZE] [/COLOR] Look similar to my plugs with 22k miles. My plugs are a little more consistent gray on the porcelain area though. [/QUOTE]
