Mr. Carb Posted March 3, 2006 Share Posted March 3, 2006 What normally causes this problem on an ea81 engine... Piston #1 isn't fireing unless it's reved up to 2500+ rpms. I've checked for vacume leaks, all 3 other pistons are fireing just fine. Theres spark on piston 1's spark wire when I unplug it. SO I'm not sure at this point what causes this kind of behavor. Any ideas? Link to comment Share on other sites More sharing options...
carfreak85 Posted March 3, 2006 Share Posted March 3, 2006 Check your ignition system. Plugs, leads and distrubutor to see if they need to be replaced or repaired. Link to comment Share on other sites More sharing options...
