my car keeps missfiring,i changed the spark plugs,ithey are brand new champion iridium,im not too sure what brand that is,have apc spark plug wires 9.3 millimeters,they are about 4-5 months old,what could be the reason why the car is missfiring,i gapped the spark plugs as suggested,my car is a 96 eclipse gst but with a 99 gst motor but the turbo is from the 96,the turbo runs good,but it begins to missfire when it hits the turbo around 5 lbs.so i cant run it to its full potential,i have a brand new holley 255 fuel pump.can somebody please help,what should i do,or what can be wrong,list them all if you can,ill fix it all,the car runs realy well when the turbo doesnt kick in,it only missfires whenthe turbo hits. thank you
