This problem is VERY OLD. If you look at my first post, this car did this even in warm weather. Heck it did this in Arizona, so it's not the cold weather. I just didn't want to start a new thread, so I'm continuing this one.

Earlier I reset my base timing to +5 BTDC. Then I bought 2 cans of MCCC. I sprayed one completely through the PCV valve. I could only do it in 1 minute spurts though, because after about 1 minute, I couldn't hardly breath due to a beautiful exhaust leak right at my O2/DP flange. But anyway, I did that, let it idle for like 10 minutes, then took it for a ride around the block. I did see a slight improvement. I came home, parked it, pulled the plugs, and sprayed the 2nd bottle evenly into all 4 cylinders. I will let it sit overnight and clean it out tomorrow. If it's still there, then I will make sure I get that knock sensor tighted to EXACTLY what it should be.

Then if it's still there, then I will go ahead and throw some high octane gas in there and see what happens. I still don't think I have that loud of lifters, but if it's still there, I will get the new lifters. I am running plain jane Valvoline 10W30. I know Hughes is a fan of using thicker Rotella, does anyone else reccommend switching to a thicker oil? I did use Rotella once, but seemed to notice higher oil pressure with it and was a little worried about it. But maybe I was just being a chicken.

Anywho, I will write back once I see what happens tomorrow!
