'76 California 2.0 F.I. stock, 119,000 miles, passes smog every 2 years. Using 89 octane gas and Brad Penn 20/50 oil. Engine starts and runs well, but lately the engine has been "rough running" on for one or two seconds after ignition shutdown. Any thoughts on what might be causing this and what I might do to fix it?

Run on is most likely cases by a vacuum leak or fast idle. Aftermarket ignitions can keep power applied after key is off too and run on or partial run on. Check with manufacture of device

Check with manufacture of device -Robert Thanks, in my case, I think that's what's causing it. I have a Crane XR3000, my 2.0L does the same thing, especially if the idle is a bit high. I stop it from happening by putting it in gear and doing a slight clutch release when I key off. |
