Hey guys, back with this eclipse.

(Sorry about the post here, but I can't post anywhere else yet)

Recap:
2G 2.0 DOHC n/t
New head, all the gaskets, MAP, crank, and cam sensors, throttle body, timing belt and tensioner, fuel pump filter and relay, ignition switch, ignition pack, plugs, wires.. I'm sure there's more... I also took off and cleaned out the egr (which helped with the idle)

My problem is with the throttle. When I start it, it idles fine around 1k and drives fine for a few min. Then after you stop and it idles, it starts acting funny. You hit the gas and it hesitates to go for a split second before jerking you forward and accelerating. You get the same effect when you let off the gas as well.

I put a video up on you-tube of it idling and me explaining my issue. Feel free to check it out.

Any ideas?
 
Was the TPS installed properly?


For you and laser5spdturbo both, the TPS is attached to the throttle body. It's got two T-20 screws that I don't think are meant to come off... I broke 2 bits trying to get them out. Anyway, so I have changed the throttle body (therefore TPS and IAC) 3 times and it still acts the same.

I am starting to wonder if it has something to do with the FPR...
