I keep getting radom misfire code p0300 I have the AC delco iridium spark plugs & expensive taylor wires been in for only 25K miles.

the code appears (chech engine lite) then go'es away. zero preformance loss.

anyway I'm planning a spark plug swap w/ the NGK TR55 is the 55 the gap?

Stock gap is .060 so any where in between is ok with a few mods

Yes they do

Another TR55 guy here... .55 right out of the box. always helps to check though!

Exactly! Mine were right on. Just be carefull checking them. I eased the gap checker on and it still managed to hang and get stuck between electrobes . No stratches or damage thakfully.

I changed the plugs and am still getting the check engine light.

first day no light thought I fixed it second day dam check engine light comes back then goe's goe's off for a few days.

when I install spark plug wires I make sure they click once one the plug and twice on the coil.



are you suggesting to check the wires with a multimeter?

these are preuiem taylor wires.

Thanks
