Check your airfilter and airflow system hoses for leaks. check sparkplug gap and spark . Connect the sparkplug to the wire and place the sparkplug on a metal (grounded surface)and turn the engine. it you should see a strong bluish spark. If it is not good, yellow or weak, replace the plugs.Check the gap for your particular engine and see if that helps.If that does not help try cleaning the MAF sensor. (Mass Airflow sensor) If it still does not work you may have to have a mechanic check the coil or check your motor with a scanner.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

1991 VW Cabriolet runs rough during idle


Check the hose between the inletmanifold and the pipe to the brakeservo it normally gets old and a crack in so the engine sucks false air on cylinder 4, causing engine to run rough or uneven.
