Matt64341 Posted June 28, 2008 Report Share Posted June 28, 2008 For the longest time I have had a very intermittent misfire. Originally it came about and I didn't see it for six months or so, and then it began to happen once every one to two months. Finally I got it to throw a code (P0304). I switched the coil to cylinder 2 and have been waiting for the light to come back for P0302. But the misfire only showed up very rarely and lasted for a couple of minutes until the engine was warm so it never gave me a code. Finally, today I got a CEL that confirmed a bad coil. But while waiting for the Cylinder 2 misfire to show up, I read that the owner of another 95 had an engine that would not start after swapping in a 3-pin coil in place of the 4-pin. I have heard from other places that they are all compatible. Has anyone put a 3-pin coil in a 95 and had no problems? or can anyone confirm that I will need a 4-pin?

///BHRpowered Posted June 28, 2008 Report Share Posted June 28, 2008 hmm, frank might be the one to speak with about this, I know he was chasing a coil for awhile. IMO your better off replacing all of them, or atleast half at a time, your already in there, and if one went bad the others will go in time.

SteveSter Posted June 28, 2008 Report Share Posted June 28, 2008 From what I hear 95-96 can only take a 4 pin and the rest can take either the 3 or 4 pin coils. If you look on ebay sometimes they sell 6 4 pin coils at a time. -Steven Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted June 28, 2008 Report Share Posted June 28, 2008 Matt - I think I remember you having a 95, if so the nI would get this at this price http://cgi.ebay.com/ebaymotors/1995-OEM-Ma...sspagenameZWDVW can't go wrong for under 20 bucks shipped Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted June 30, 2008 Report Share Posted June 30, 2008 infact, you should attend MWM08 with it Quote Link to comment Share on other sites More sharing options...
Matt64341 Posted July 24, 2008 Author Report Share Posted July 24, 2008 infact, you should attend MWM08 with it Sorry, I won't be able to go to MWM08, but a later year is a possibility. I also wanted to update, I won the 4-pin coil off eBay for $19 shipped and it is installed. So far, I haven't had any problems with it. If I get a chance to get a cheap 3-pin coil at some point I will test it in place of a 4-pin to confirm whether or not it is compatible with the 1995.

After my first coil failed i bought 3 spare ones just in case. I asked the guy to send the front bank coils which are less abused.mI recommend you do the same.

That is a good idea, I am surprised that I had a front bank coil go before a rear one. The rear coils see a lot more heat. I fully cleaned the old coil to keep as a spare since it works 98% of the time. I also tried to measure the resistances. I was able to get a value for each set of pins, but the meter I used was digital and the resistances were strange, so I will need to find my analog meter to retake them. From the wiring diagrams it looks like: Pin 1 is the charge wire Pin 2 is only in 95 Pin 3 is the trigger signal from the ECU Pin 4 is a ground Coil Diagrams The 1996 and 1997 diagrams don't include a second pin so I am not sure what it does on the 95.
