ANOTHER CODE ?

went outside to check a few things & its bringing up PO356 & PO 355 any ideas

When you say new coil packs you have a 96-98? Check the plug wires first, then the plugs. Probably something minor.

Coil on plugs the 35x code usually means on the supply side of the coil. Make sure they are secure on the plugs. Also check the plugs and make sure they are tight. Almost sounds like you are losing the connection in some fashion.

What brand of coil packs are they? I had some granetellis and they went bad in less than 1k miles.

I was just about to mention the Granatelli COP's. Also, unplug them all and try hitting them with some hot air from a blow dryer. I unplugged mine recently for extra room while installing/uninstalling a new intake manifold and I was POSITIVE I didn't get any water in those things but still got the misfire code. I unplugged them all and blew some warm air in for a bit and cleaned out with dry rag and the issue disappeared.
