Anyone got a MAF??
Well, I am still trying to track down the evasive KR in my 01. I would like to swap back to a MAF that still has the screen. Does anyone have one for an 01 or 02 that they would be willing to sell, trade or loan?
I really don't want to buy a new one if it doesn't make any difference.
Thanks

K/R comes from a lean mixture. Get a MAFT and Dial in some richness. You'll be glad you did! Otherwise there is nothing gained by going back to stock.

Before what? The first round of head work?
I think we are now square on the headwork- And yes, I still feel like Chris Farley, "Stupid!, Stupid!!!"
Anyway, the Dyno was showing way rich down near 11:1. But we had a valve that wasn't seating and a broken rocker during that pull.
I ran the tank way down and filled up with Chevron 93 (after driving to Garland to find Speedtek was out of 100 Unleaded). I usually buy Exxon 93. On the way home, I didn't see any KR in a few WOT blasts on the Chevron.
I'm heading to Hallsville tomorrow for a few runs down the 1320. I might try some 100 if they have any. We'll see if the knock is real or false.
Here are the chronicles...
7/2001: Dyno Day: No knock, 328/343
12/25/01: Blow Shift, Dealer Attempts to fix
1/19/02: Supposedly fixed valvetrain, Donaldson, No Screen, Z06 Exhaust, 326/343 Erratic Curve, Rich, Plenty-o-KR between 5000-6000 RPM
1/26/02: Swap plugs to TR55s, KR up 3.1 deg in same RPM range
2/6/02: Dealer finds bent valve and broken rocker, replaces both, downloads software updates for KR reduction
2/7/02: KR better, still see 3 deg in 1 out of 4 runs.
2/10/02: Switch to Chevron Gas, engine pulls strong with 0 KR (not enough runs to conclude a change)
