Whenever I decelerate or shift into neutral or park my RPMS SPIKE 500-1000. Different mechanics have told me different things. I have automatic 4cylander sc1. The dealer said it needed a new intake manifold gasket, so I had that done. Didn't work. The next mechanic told me it needed a tune up, new plugs and wires, valve cover gasket, crank position sensor, and idle control valve. Did all if that--still didn't work. When I pressed him as to why, he just said that it is normalnd all cars RPMS spike when you shift due to the engine loading when you shift through the transmission. Here I am $1000 laer and no better. Please help!
have the same problem?
