I'm near South military highway Right on Bainbridge I really hope they came pregap i payed 11$ a pop for them but I will check. I'm going to take my valve cover off and inspect a little.. I'm doing a little research on valve adjustment and give it a try.
DTC p0300 - Random misfire
DTC P0172 – Fuel System to Rich
DTC P0301 – No. 1 cylinder misfire
DTC P0302 – No. 2 cylinder misfire
DTC P0303 – No. 3 cylinder misfire
DTC P0304 – No. 4 cylinder misfire

Those are the codes I've been getting

Check power to the coil packs. Something is affecting them all at the same time, which means that moving coil packs around or replacing them isn't going to help at all because the coil packs are not the problem.. Also check your engine grounds.
Might be an engine position sensor, but you'd normally get occasional or persistent CELs for that. There would be some stored codes.

Have you attempted to clear the current DTC's to see if they return? As "Fabrik8" said, check for voltage to each coil. If you are getting power there then we can move on. Do you have an aftermarket throttle body along with that manifold?

CharlieSheenDc5

yes cleared dtc every time i have fixed something i thought could be the problem. ill also check for voltage i have not yet tryed that. . my battery recently went bad on me from the having to restart car after every stall but i will be getting a battery tomorrow and go from there. really appreciate the feedback guys!

No problem man keep us posted.

CPS sensor.

It's almost has to be a time issue. To be missing on every cylinder. Crank/cam position like DP said.
Also could be a bad ecu. I've had a similar issue with a vehicle from the ecu just dying literally overnight. Ran like absolute shit for a week then wouldn't start at all. It threw codes for every single sensor on the engine the last few days before it wouldn't start at all.

Correct me if I am wrong but if the CPS is bad the car wouldn't start. If it is not holding an idle on a cold start as I've stated I would definitely have the valves adjusted. Also you stated you could drive it if you held the throttle, is the car missing while engine is cold, hot, or both?

Born-Sinner

I would see if the PCM has been flashed or has gotten wet somehow or also use a known good PCM. Just don't throw anymore parts at it.

forgot to mention that car idles normal once warming up, does missfire slightly but progressivly gets worse at it warms up.
