'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?
