Def let us know. Hopefully that's all it is. Checking the battery and alt couldn't hurt either.

so i cant get my fuel filter out. i almost made my hands bleed trying to push that fuel line disconnector tool into the clip. any thoughts on that?

Keep trying, is it right size? Maybe try one bigger so it wraps all the way around. The plastic ones usually its size bigger then you squeeze it together. Also try twisting it while pushing.

mine had this issue recently my car would idle terrible and stumble at wot really bad. try checking your cop connections where they plug into the wiring harness and see if there all tight also you can pull a few of the put and see if there terminals are corroded also. and if that doesnt work you can pull out a few spark plugs and see if there dirty or black and clean them

I notice you said u had cams in the car. When I put my comp 270s in I had to have the tuner turn off that code. The computer will through the code due to the different cams.

If its been awhile since the fuel filter has been removed spray some pb, wd40, etc in the spring lock/where you put the tool. That generally makes it easier for the tool to release it and for the filter to come apart from the line.
