is there a way to fix an erratic idle on an 88t2 motor without changing the throttle censor. ill be gettin 1 if i cant get it to act right. i have a j-spec and can just turn the idle up , but thats not really what im lookin 4. can u help , or lead me in the right direction. thanks

 

Have you checked all your sensors? TPS, Rad Temp, Bac Valve working correctly, settting you idle to FSM? What exactly is the idle doing? What rmp range?

 

in between 9 and 12 grand it braps never choosing where it wants to stay. how do u check those sensors.

 

Ok, does it continue like that, or when it warms up does it drop to a steady rpm. You in the bay area?

When you first start it, what happens to the idle?
When it is warmed up, what happens to the idle?
Is you car stock, or emissions and such removed?

The best way to check them is per the FSM. Factory Service Manual. Look for threads where Hailers, or NZConvertable, or Wayne88na have chimed in on regarding your situation. These guys are brilliant. Amongst, many other gurus here!
