Default CEL with 4 Codes Thrown

I went to start up the car yesterday and then engine was cold so I let it warm up. It usually does so around 1500rpm. When it got to 1000rpm it was chugging a bit so I revved it, not hard, once and it went down to about 500rpm and stayed there. Only thing was the CEL came on.

I get one the highway to go home and there is this strong smell... I couldn't tell if it was fuel or not coming in through the car everytime I moderately pushed the car to get on the highway.

I check the codes and it is P0301, P0302, P0303, and P0304 which is all 4 cylinders misfiring according to the code reader.

I had an 03 Lincoln LS V8 which was notorious for blown coils since the valve cover gasket would leak and let oil into the coil on plug wells. When even 1 cylinder had a misfire the CEL would flash (which I thought all OBDII cars do when there is a misfire) and it would buck like a bronco letting me know something was wrong everytime I gave it gas. The previous owner did install an Exedy Stage 1 clutch, resurfaced the flywheel and put a new pilot and throwout bearing in.


Wondering any possible causes and solutions. This happened right after I put a strut tower brace but I can't see that affecting it. The PO put a CAI on the car that draws air from the front of the wheel well but that has been on there for a while. I haven't checked if the filter element is clean though so should I check the MAF and ditch the CAI?

Any help is appreciated... I'm very new to this car.
