i had a bad throttle body and tps.i just bought a new throttle body with all sensors and put it on today. it still seems to lean out real bad in my high rpms. it doesnt do it as much with the new throttle body but i was wondering if anyone else had that problem.

 

a better set up description may help

 

what car, what fuel setup, etc. are you running and why do you think its lean?

 

if your judging by one of those storkiometric(sp?) gauges then i really honestly wouldnt trust it unless it was a really expensive one with a good set-up. aka, not just the autometer hook-up thing. its basically just a nice little rainbow gauge from what i've heard.

 

lol... What he needs is a Wideband.

 

its a 90-93 ls motor... i thought it was the tps because my check engine light starting coming on right when i noticed it leaning. when i checked the check engine light it said tps. i was having other problems with my throttle body so i went ahead and just bought another one. it was used but its still better than what i got. it fixed the light, the surge, throttle sticking, and it made the leaning out better. but it still sucks. its an autometer gauge so it oculd be lieing to me but i can smell it in the high rpms...starts from about 4500 and the guage works its way down as my rpms go up...it gets to where theres nothing even on the screen and picking up speed is terrible...

 

my step dad which is a mechanic said that your fuel filter might be restricting it. that and you might need a biger fuel pump.

 

that sounds like it could work...ill try the filter first and see what happens. might have a civic filter or something.
