Check engine light popd on and this code p0340 popd up being the cam position sensor. Ever simce light came on engine shakes a little around 2000-2200 rpm but drives fine
Cleared the code and swap a workin sensor and still is doing the same
Read on another forum that this code is also caused by the alt going bad or its internals something along those lines
Bo hesitation on start up and drives normal besides the shaking around 2k rpms
Any advise and help is appriciated thanks cafords!!

yep bad diodes in the alternator makes it still charge fine but cause radio interference problems (rfi) that causes a bad cam semsor signal even though the sensor is opperating fine, it will also cause coil problems from time to time. but sounds like you just have the alt problem. the aftermarket alternators tend to overcharge and swell the batteries too. but are quite a bit cheeper
