az trzy 420 SEL z 1986 roku w jednym watku, a ponizej fragment wypowiedzi goscia, co zrobil zeby to wymacac:
I've accumulated a collection of 4 idle speed controls, 3 idle control valves and 3 ovp relays; none of which seem to be my problem. I've also replaced the following: ignition control module, cap and rotor, spark plug wires, spark plugs, fuel pump relay, fuel pump, vacuum hoses, and a new ABS unit (ABS brakes weren't functioning as they were supposed to). I'm getting so many parts from the junkyard I could build an entirely new engine. Although, I have yet to replace the throttle position switch.
