Q: Rough idle and car cranks but doesn’t start up EPC Light is on

asked by on January 10, 2018

My car hasn’t been having some rough idle issues, it started a while back and I would give it some gas and it would fix the rough idle issue. Now it got more severe to the point where the whole car almost shakes when it’s idling. The car would also sometimes start up and sometimes wouldn’t start up, it would crank but not turn on, it would take a couple tries to start it up. Once it does start up, the engine just has a really rough idle. The rough idle would go away as soon as I would give it some gas, it would go away once the RPMs were above 2,000. The EPC Light would also come up but go away once I go past 2k rpms

I changed the crankshaft position sensor, the camshaft sensor, And o2 upstream sensor, I don’t know what else to do.

The codes I get P0016-crankshaft position sensor P0300-random/multiple cylinder misfire C342D-manufacturer control P0055-H02S Hester resistance bank 1 sensor 3 C3064-manufacturer control

Thank you!!
