My apologies for the length of this.
Pulled distributor to change the condenser. Reinstalled and reconnected all wires and plugs. Static timed it and think it's close. Started the car and the idle slowly raced up to 3000 rpm and stayed there. Did this a few times with no change. Turned the idle adjuster screw to get the idle down. Restarted the car. Idle was lower but car would run for about 10 seconds and die Working the throttle had no effect. Engine would die. Changed relays on the relay board. Changed fuel injectors. Fuel pump has power. All vacuum hoses are fairly new and fit tight. Car is now at a reputable shop and has them scratching their heads. Does anyone have any ideas on why this is happening and what should be looked at next? Would REALLY appreciate any thoughts, insights, and direction. Thank you in advance. EJP914 |

Maybe the AAR (Auxiliary Air Regulator) is not working properly.

I would a disconnect the retard and advance and if it still climbs try retarding the timing a bit. Have you checked for vacuum leaks?

Thanks for the replies.
Will check on the AAR valve. No vacuum leaks. Hoses are new and tight. Will look again at timing. |
