my coupe stumbles at high exceleration. i recently changed vacuum advance, checked for any vacuum leaks (none). i had the petronix ignitor put in and retimed. i put an in line fuel pressure gauge and it reads around 5lbs at idle but the needle jumps up and down like crazy! any thaughts? oh yea, my carb was suposedly recently rebuilt but i have to spray carb cleaner to start up on the cold start.
