my tach is bouncing around from 1.5-7k happens mainly after the car warms up. the motor is a b18a from an automatic, mine is a manual. this is something that just happened in the past two days out of no where.
I have reset the ECU 3 times now, and it's still happening, i'm replacing the distributor tonight (eraser:"it's always the ignitor") , yet is there anything else i should look in to?
i don't think it's going to be my fuel, but i don't have the ERG set up to anything since it's pretty much only needed for automatics. I dunno throw me some cheap options

 

code 43 = Fuel Supply System defective or malfunctioning fuel supply system

 

i think i got that cel...it was o2 sensor
