i have a gsr motor and i just swapped throttle body from a 95 gsr. when i drive normallly its fine then i got on it and the cel came on and the car started sputtering..... im having my mechanic scan the cel.. but it has to be related to the throttle body because it happened right after and the car was fine when i started working on it... i replaced the map sensor on the throttle body but not the tps.. could the tps cause this to happen it only throws a code when i hit about 6000rpm..? i checked the tps by taking the plug to the switch off while the car was running and the cel came on. so its not completely bad but could the voltage be off or something.... ?
thanks wes

 

BTW when i start my car up now the idle doesnt shoot up to 2 grand or so when its cold just idles at like 1k all the time.....

 

my bet would be a TPS sensor

 

thats what id like to hear considering thats the only sensor i used from the used throttle body....im going to let my mechanic scan the code tommorrow morning ill post up on what it is.... im sure from going rich the hesitation and sputtering is from fouled plugs.. i have like 12 backup plugs so oh well...

 

i didnt get the computer to scan and the tps is a bitch to get off did i mention i have a donor throttle body and i had to hacksaw it to take it out with a flat head... i really hope this is it ... any one else have any idea... my key thing is on a cold start the idle doesnt go up just stays at 1000...?

 

bump.... can someone help me out?

 

im thinking its something besides the tps sensor my problem is stated above someone please help me out i dont wan to swap the tps if i dont have to its a biotch...

 

...

 

any takers?

 

was the map sensor
