Q: RPM gauge acts crazy, spark knocks, skip then shut down 2001 Hyundai Sonata

asked by on January 14, 2017

Crank, cam, mass air flow, both coil packs, fuel filter, spark plugs and wires, and timimg belt have been changed. But once it drives for about 10 miles (depending on temperature outside) it starts spitting and rpm gauge acts crazy then shuts down. Takes about 2 hours before u can drive it another 10 miles.

My car has 175000 miles.
My car has an automatic transmission.
