Misfire at Idle...
Alrighty well the problem I'm having is the car misfire's at idle.. I have replaced the optispark, plugs, wires and ign coil about 4000 miles ago I have also replaced the fuel injectors with new ones in hopes of squashing the idle problem. When I hook it too the OBD II scanner I will have the 0300 mulitple misfire detected pop up or sometimes when I clear it a 0307 # cylinder 7 misfire detected will happen. However the engine will rev with no problems and I can hold it at about 2000 RPM with the code not coming up but once its sits at idle for about ten seconds or so bam there it is and I get the misfire code.... I don't belive it's a problem with the optispark or ign as it revs up with no hesitation.... Any thoughts?
