Well I did some work on the TB and think I screwed up the plate. I tapered the entrance hole to accomodate flow better and pulled the plate off to taper it also. Well i tapered the front side top and bottom(idiot). So now the bottom doesn't seal properly. I had made sure I didn't mess with the diameter by filling to much of the edges off, but didn't take the time to realized that it being on a slant, the plate seals on the front side of the bottom and the back side of the top.

I took it for a spin and throttle response was better but while sitting at a light the rpms start to rise and car jumps into limp mode. i pull over, shut car off and check what I can, restart and everything is fine for a bit, until i sit at another light, and same thing. I cruise to the local AutoZone and get the codes for throttle position sensor and higher than normal idle.

I feel like such a novice when I do things before thinking them out properly. I pulled the neg off the battery and will pull the throttle body off again to see if I can correct the plate any.

I am having a hard time with this being my problem. For instance, with carbs you can drill a hole into the throttle plate to level out the A/F adjustment if you have more fuel and need more air than the screws allow. i am curious if the ECU will correct this any or if the plate has to seal completely due to vacuum readings? Someone please give me some pointers, or advice or anything that will make this go well for me, lol.
