I live in Australia and have a possible faulty BOSCH Distributor in my 1984 Falcon.
The Engine is a Carburetted 3.3 litre version with Electronic Ignition.
What are the symptoms of a faulty Dissy ?.
What is meant by a 'curve' ?.
Electronic ignition doesn't have a Dissy as such, its a different set up the the old Distributor Cap that you know.
To Diagnose Electronic ignition you will need to use a 'Multi-Meter' to test the spark power or just take to any Auto Electrician to test it for you.
Old method of testing is:
Remove spark plug from engine to see spark jump while turning the engine over (requires a 2nd person)
do this to ALL 6 spark plugs to ensure spark on all lines, a weak spark can also be caused by a cheap or worn lead.
providing you have good spark & plugs then you'll probably find its the Electro-ignition solenoid. (the little black box that the leads come from)
Auto sparky will verify that in 5 minutes.
So there ya go...
Whaddya think of that,... Batman.!
