My 99 tahoe started jerking about 2 weeks ago after hitting a deer on the front driver side. The jerking started off gradually and has progressed. The rpms will rise & drop and the vehicle will in some cases cut completely off while driving. The jerking occurs after a few minutes of driving. The check engine light doesnt always come on and today the ABS light came on(Clueless) Replaced cam shaft sensory and dropped the tank and checked all hoses. Im thinking It may be the pcm! PLEASE HELP!
