Hey guys, I just installed a ck shift kit and everything works great. I've driven around town for a few days but today I got on the freeway for the first time since the install. When it's in overdrive and I'm just cruising, the engine bogs down then up and continues this pattern every few seconds. The check engine light almost comes on but then goes off simultaneously with the surging. So it does not throw a code. I caught the activity on my powerlogger and when it bogs down, my tps is right to 0 then back up. Same with the int and blm's, they go to 0 when it bogs then jumps back up to normal 128. What could cause this? WOT seems unchanged and cruising in any gear besides overdrive is fine also. I can only replicate the problem in overdrive.
