Help – Engine stumbles erratically
I have a 91 RS with a 305 TBI motor. Overall the car runs well, however sporadically the motor seems to stumble. It feels like fuel delivery instantaneously stops then resumes. It seems to occur randomly under both light and heavy acceleration. Any suggestions on what to investigate? I thought maybe I should check the IAC value. Do they get dirty and malfunction? Thanks for any help.
