Engine skip

[92Talon251]

It seems when I start my car and let it idle down to 750Rpms, every now and it is completely random the engine just skips it idles fine. Then for 0.15 of a sec your hear nothing then the engine idles again keep in mind this is random i think it might be timming but not sure.

umm misfire, same thing happened with my car when i first bought it....
plugs were gapped wrong.

Thats is what I thought to so I re gaped the plugs back to .28 i still get the same problem the sparkplugs are brand new as well.

I have even gone as far to replace the Ingition coil (2 months old), the plug wires (1 year old), and the plugs (3 days old). I still get this "misfire" I dont get and CEL codes either the light hasnt came on. It might be the ECU any one ever had to replace the ECU to fix this?

I have that same problem as well. It only does it at idle for me, as well. I have new NGK plugs/wires gapped to .28 and it still does it. I'd also like to know why this is happening!

Just pulled the sparkplugs out 2 of them where gaped to .25 I dont know how this happend I gapped them myself to .28 and checked them 3 times for before installing. I regapped them to .28 again, ran the car today still getting the skip. It is either my bad luck or the ECU I guess??

Sometimes when puttin the PLugs back in they may hit the top of the hole and mess up the gap....so be veeeeeeeery gentle when dippin those babies in there.

Well I fixed my gaping problem. I recomend to anyone having trouble gaping sparkplugs to buy the other type of gaping tool unstead of the sliding one. The other type should look like a circle with wire loops around the outside. I used both gaping tools in conjuction to make sure I had .28 on all 4 plugs. Of course I was obsesive just a little I hated that skip.
