Q: Q: No acceleration

asked by on

Got codes 33 35 56 55 63. Runs for awhile hard to start no acceleration.

My car has 154623 miles.
My car has an automatic transmission.

The list of codes you are getting point to different sensors. Code 55 is a computer error code and so you may have a computer failure.

I would first look at the computer under the hood to see if it has bad connectors in the wire harness and/or problems in the wire harness itself. The vehicle may have more than one problem and would need to be looked at by a qualified mechanic. They will be able to diagnose the codes you are getting and fix your acceleration problem.
