Engine drag

I screwed with my TPS the other day and tried to set it. I didnt get it right but I ended up eliminating like all my engine drag. My car coasts without trouble now and it does not feel like its going to stall at lower RPMS in first or second gear. also when i downshift the engine does not brake much at all, Is this bad for the engine? I'm going to get a different ohm meter soon but I just wnated to know if it is bad for the engine to have very little resistance when i let off the throttle

those are the signs of a properly adjusted tps. this comes from the engine not trying to cut feul to one or both rotors as often. i just adjusted mine and it realy helps smooth thing out, especialy at low rpm/load.

If the TPS is adjusted to not show closed throttle to the ECU, it may hurt your fuel mileage.

It will be feeding some fuel on deceleration.
If that's what you want - your choice.

Gettin any flames out the back?

The injectors should shut off any time you lift off the throttle. If they don't, the TPS is not set properly.
