    I drove it Sunday to a restaurant and everything was normal and when I left my shifter (manual) was shaking extremely bad in second gear and all the gears after that point. I drove it home and it felt like it was not getting power and was misfiring pretty frequently. scanner picked up a cam shaft sensor code and later when I made it home a cylinder 2 misfire code. I replaced my camshaft sensor (it appeared to be leaking oil) and changed all my spark plugs. now i am only getting the cylinder 2 misfire code and it barely runs when idling. I did a compression tests on all 4 cylinders and they all were 205-210. What should my next step be? Coils and wires and then fuel injectors? If a coil was bad would I not get 2 misfires? (1 coil runs to 2 sparkplugs).
    I changed the MAF sensor, both 02 sensors and pcv valve about a year ago. Any advice would be appreciated I am not super mechanically inclined but consider myself a DIY.

    Could be bad injector. If you start it and it runs good then misfires a little later when you restart it while warm its more than likely a bad injector. Troubleshoot it completely before buying a bunch of parts as that is the worst thing to do.

    It runs pretty much the same cold as warm.

    Many years ago I had a sparkplug that part of the electrode tip insulator broke off. It made that cylinder misfire badly.
