98 cavalier TDC sensor?

Asked by AliceHManson Oct 03, 2021 at 07:30 PM about the 1998 Chevrolet Cavalier Coupe FWD

Question type: Maintenance & Repair

The check engine light is on and the code reader says 'can't read top dead
center'.  What does that mean?  I just changed plugs/wires, then check engine
light starts coming on, idles rough and vibrates.  Surges with acceleration and
feels like its losing compression at times Then will suddenly take off and be
great, just a little bit though.

Take a look at what you did to replace the plugs and wires. You may have knocked something loose or miswired the plugs and/or wires so they are not connected in the correct firing order.
