Any new info on this one?

My father's 96 E300D (w210 non turbo 606) has a CEL that comes on for the throttle position sensor. I replaced the unit up there by the brake booster (throttle wire, a linkage and an electric circuit all attach to this $355 part), but then the light came back.

Originally it seemed to be caused by using the cruise, but now its come back without cruise usage. I have to guess that its something to do with the wiring, as I can't imagine the MB part was bad (maybe not the old part either).

I really need to get this TPS code to stop coming on, so thaqt I can get the car inspected (code=automatic fail, and I cant get it from home to the station without a code coming on).

We have no surging, but maybe the resonance flaps are sticking (I took the intake off and there was a LOT of gunk in the ports, and since Ive cleaned it all out, probably loosening some of it, now the egr valve sets a code, which it never did before, telling me that is probably a bit clogged). Would a sticking resonance flap cause a CEL for the TPS?

Oram I looking at a pump problem that will require a pump adjustment or replacement?

Any help would be most appreciated. The car really needs to be inspected, I cant and Im at my wit's end for fixing this thing.

Thanks,

JMH
