i have a 92 jdm b16a and my throttle is very sticky...almost every time i give it a Little gas the tb gets stuck..ill be totally off the gas pedal and my vafc will read like 4.3% throttle or whatever i was last at..i tried cleaning it and it didn't help at all so im thinking about just buying another tb and sending it out to the big bore throttle body guy here on h-t to clean it up really good bore it out and set the tps to spec, im just wondering if there are any other throttle bodys that Will fit on my 2nd gen jdm b16a, also what gasket would i use?

thanks-johnny

 

is it reading closed when you first start the car? You might just need to recalibrare the TPS

yes, recalibrating the TPS would get rip of the problem with the VAFC reading 4.3% open with a completely closed throttle but, it wouldn't fix the sticky throttle problem.

what i did was, i took off my friend's throttle body and adjusted the nut on the bottom of the throttle body that acts as a stopper for the throttle plate.

there should be a stud and a locknut below the throttle plate. i adjusted it enough so it wouldn't stick and to not adversely affect the idle. adjust it so, it wouldn't stick and when you put it up against a light, there is no or very little light showing through the edges of the throttle plate.

 

when i start it up it reads zero % throttle so i dont think its my tps, also i checked it on my vafc and its reading .45 closed throttle and 4.5 wot(if i rember the numbers correctly)

 

Those voltages sound right, have you made sure it isn't the throttle cable that is sticking? otherwise you can try adjusting the throttle stop screw like the dude suggested.

 

like i said, the TPS voltage has nothing to do with the sticking throttle body. read my entire post and maybe it'll help you out.

so was the plate actually getting stuck on the stud?..sorry man i read it but i wasnt really comprehending it until now

 

up

 

again

 

Jus tget some throttle body cleaner or sea-foam and it'll take care of that in a jiffy!!

 

If you pull the intake off you should be able to tell by looking what it is sticking on. If you unhook the cable and it moves fine then you know thats the problem, otherwise you may just have to clean it like the guy said.

no it isn't stuck on the stud but, the stud on the bottom of the throttle body regulates how much the plate is actually opened at completely closed throttle. so, if you raise the stud a little and lock it with the lock nut, the plate will rest on the stud

 

where can i get sea foam?.....and what gaskets are compatible?
