Misfire #1 after intake gasket replacement

[bbunn1]

Well, I finally replaced the intake manifold gasket and my coolant leak is resolved. However, I now have a P0301 code coming back and a noticeable miss. My little OBD scanner shows 2 codes (P0301 and P0301 P), not sure what the "P" means. I'm thinking 2 things here. 1) the fuel injector at # 1 is either not connected correctly or it's plugged, 2) I torqued the rocker arm(s) at #1 too tight and the valves are not closing all the way. I'm about to do a compression test to verify this...does anyone know what a 2000 Malibu cylinder should read on compression?

Also, the CEL stays on continuously when idling or low speeds but when accelerating it will flash...does that signify anything?

Thanks!

When your CEL light comes on it and remains lit, it means there has been a fault, and there is a code stored in memory.

When it flashes, it means the car has misfired , as for the miss, I would check out the plug first. It might give you some insight. Then the fuel injector connector.. Easiest one first, right?

Yeah, normally I would check the plug or wire first but just prior to replacing the gasket I replaced all plugs and wires and all was fine for a few weeks. The misfire started happening after the gasket replacement which leads me to believe it's something I did during that ordeal. I'm wondering now if I connected the #1 fuel injector wiring completely. I guess I'll find out Friday.

Thanks for the clarification on solid/flashing CEL!
