milkman111083 Posted November 18, 2009 Share Posted November 18, 2009 i was having a misfire issue on a 2000 rs. so i changed the spark plugs and the cylinder 4 plug was fouled. it ran great for about 200 miles and then fouled again. Im going to replace the wires today but the coil pack costs 150 dollars. is there a way of checking if the one i have is functional. Quote Link to comment Share on other sites More sharing options...
mikec03 Posted November 18, 2009 Share Posted November 18, 2009 Well, I sprinkled water on mine and it replicated the problem. So you can try that if the coil is the problem Otherwise, I assume you have a 2.5 engine. If so, the spark plug tube gaskets are common leakers. The oil drips from the tube gaskets saturate the wires which causes misfires. Quote Link to comment Share on other sites More sharing options...

tcspeer Posted November 19, 2009 Share Posted November 19, 2009 You can check the coil pack with a muti meter, and a haynes manual. the instructions in there are real simple to follow. Quote Link to comment Share on other sites More sharing options...
