rayaapp2 Posted January 3, 2009 Share Posted January 3, 2009 I just changed my plugs out and found corrosion around the old plugs. I cleaned the head surface and the isolator boot on the coil packs off pretty good. I noticed that after the car came up to temp that the engine still has a miss. So I stuck my head down by the valve covers and I could hear noise around the rear cylinder COP's. I thought it was coming from either cylinder #4 or #5 so I took it back apart and cleaned the area up as best I could. This time I washed the areas with warm soapy water and a paper towel. I warmed it back up and the miss was still there. So I waited until tonight. With the lack of light I popped the hood and looked at the coils for bleed off and there it was. # 1 and #6 both have bleed off. The car stopped missing as bad, but I can still see the spark bleeding off. Its on the driver side of the coils(exhaust side) and it looks to be bleeding to the COP rails. Both are doing the same thing. These COP's are the S2 ones so they have built in Ignitors. Im hoping the COP case is just dirty still and the case isnt actually damaged and seeping the spark out to ground. Does this sound like a typical COP failure or is it likely dirty? If they have failed how hard is it to get the S2 COPs? thanks for any help Quote Link to comment Share on other sites More sharing options...

jtmny1999 Posted January 12, 2009 Share Posted January 12, 2009 I am also having problems with the coils I believe, I can hear clicks that sound like sparks coming from the valve cover. And my power drops after 5k rpm. Also after warm up it starts missing bad. Rayaapp2- Did you try that Flexane94? and cleaning out the coils with a dremmel?

The link is to an expired session. Thanks, Pete Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted January 13, 2009 Author Share Posted January 13, 2009 PART NUMBER: So I had a chat with Napa and had them call the manufacturer of the coils. They can get them, but they have to be ordered from the manufacturer. Part Number for the MCP-1330 through Napa is IC383 Quote Link to comment Share on other sites More sharing options...
jtmny1999 Posted January 23, 2009 Share Posted January 23, 2009 Well I tested my coils from 1-2, and they read 1.5 ohms. Im guessing I need replacements anyone know how accurate that FSM test is? Quote Link to comment Share on other sites More sharing options...
