It is misfiring at 1500 rpms while under a load and I can feel it surging while stopped at a stop light. Sitting still in neutral is idles great and while driving at all other rpms it runs perfect. It started with just code P340 so we installed a new camshaft so we installed a new camshaft sensor on bank 1, and also went ahead and replaced the spark plugs, a new timing belt, and serpentine belt. Since then it has gotten worse. I have inspected all the vacum lines and connection and they look fine. I am clueless.
have the same problem?
