Resistors in the ignition leads
Discussion
Do the ignition leads need resistors?
Went out for a drive, all good after winter, oil, temp & water ok, fresh tanks of petrol. After about 45 minutes started stalling off the gas & when stationary. Made it home by avoiding traffic lights & blipping the throttle. At one point I’d called breakdown, but managed to start & keep running. Seemed fine when running.
Anyway
Next day, dead & I made things better by flooding the engine…
Local mechanic came out. Identified that spark was weak at the plugs & good at the coil. New plugs & dry engine & running ok again.
He pointed out that I have resistors on all over the distributor, where the king lead connects and all 8 leads. I’d leant him my Steve Heath & he pointed out that neither the 4.3 nor the 500 have resistors in the photos of their distributors.
What’s going on? I still have extenders which I’m told are ok.
The leads are standard aftermarket. Plugs are NGK B7ECS. The ignition has been problematic over the years, I’ve lost the ignition module & coil in the past 5k miles.
This is the resistor which used to be on the king lead. And a ruined plug.
