i have a 1989 crx with a b16 swap and a few bolt-ons and its converted to obd1 the car runs good but sometimes when i get on it alittle and stop at a redlight the idle goes up and down and sometimes it quits and sometimes it does it while just idleing could it be my tps or somethings any help would be nice

 

I think what your talking about is idle surge. If I where you I look at the IAC Idle Air Control vavle. let me know how that goes

 

ok i just unplugged my coolant sensor and it stopped automatically like it runs perfect now so i guess ill try a new coolant sensor
