hello , my fiero 2.5 88 gives me a code(24VSS) after decelerating out of gear to cost ,it will not give code as long as I'm accelerating or drive under 40mph it also wants to stall when going out of gear to coast but never has died just drops to 400RPM and with in a second back up to about 850 then it surges a little 200RPM up and down ,i can't get it to idle stady , i have tried new ECM which made things a little better ,unplugged TPS(no change ),new coolant temp sensor to ecm that helped a lot when cold and warm was blowing black smoke but new temp sensor fixed that so now its only code 24 problem and idle plus wants to stall and misfiring at idel after warming up , any input would be appreciated ,thanks for reading
