Default Re: Missfire under light load when hot

I'll check the TCC switch.The coil pack is Echlin and was replaced because a terminal broke off while testing it.Plugs and wires are a couple months old.I don't have access to a Caspers tester.

No codes are showing up.The O2 sensor is 2 months old.I'll check the EGR again.All hoses are good.
If I power brake it while cold it's fine.As soon as it reaches 180 it starts to missfire,Badly!!
Thanks for all the tips,I'll check it all out and let you know.MM
