tearing off my throttle body to change my TPS sensor removed the old gasket and sealant and placed a new one on with new sealant and now it idles worse and now boggles down when trying to move threw gears and stalls out coming down from higher speeds or reverse(60-0). Has never done this till i took off the throttle body and changed out the old and put in the new.

Did you install the TPS correctly AND calibrate it?Originally posted by Mishakol129 -
no the stock throttle boddy had the tps in there to where i couldnt take it off. looked like they were riveted. so i said screw it and just put it back on and thats when the problems startedComment

Ah, I see. They are replaceable, you can cut slots on the rivet heads and back them out. You can check for a leak easy enough. Unhook the intake tube, cover the throttle body with your hand, and have a friend start the car. If it starts, vacuum leak. If not, it's something else.Originally posted by Mishakol129Comment

is it possible that some of the RTV sealant may have gotten sucked into the intake? And stickn some where blocking sufficient air somewhere and if so how bad could that get?Comment

Possible, but doubtful. Did you do as I instructed?Originally posted by Mishakol129Comment

yes and it wouldnt start. so no vacum leak comming from the throttle body at least also sprayed carb cleaner around the bay to check to c if there were other possible leaks but none stayed at the same RPMs. Funny though the rpms actaully dropped like it wanted to shut off after sprayn a lil into the throttle body thought they were supposed to raise in rpms?Comment

You are introducing a foreign substance into the combustion chambers, one that the ECU isn't expecting, so the AFR gets thrown off.Originally posted by Mishakol129Comment

got it. but wat could be causing it to bogg down when moving from 1st to second( the worst part) and then the other gears it acts like it strains to get up to speed. Im rather baffled by it cause it all started when i took off the throttle body and sealed it back up. I checked the TPS on it and it was fine. Unplugged it and it shut off on me plug it in and everything is fine idling until you tap the throttle. i noticed just a lil bit of throttle it tends to bogg down but WOT it revs up fine. This is very stressfulComment

Did you clean the throttle plate and the spring on the throttle? How tight is the throttle cable?Originally posted by Mishakol129Comment

i cleaned out the plate and spring. its not real tight had a friend tweak it a lil couple months agoComment

There should be 10mm of play (up and down). Is there a screw on the bottom of the throttle body, should be touching the bottom of the rotor?Originally posted by mrb93cb7 View PostOriginally posted by Mishakol129Comment

yup its touching the rotor and it measured right at 10mmComment

Only thing I can think of is you got some RTV in a port where the throttle body mates with the plenum. Did you replace it with another F22 throttle body?Originally posted by Mishakol129Comment

ill get another gasket and clean it up again see if i actually missed something when i cleaned it last . See if that does the trick. iv been researching all over google with the same possible solutions and talked to a bunch of my mechanic friends and it all draws back to the source of when it all started (the throttle body) so i guess its time for a new intake manifold if doesnt work outComment
