I recently replaced my valve cover gaskets, water pump, timing belt, vvti gear, spark plugs wires, and all seals. My car is now misfiring on all cylinders throwing a code of p1346, p1349, 0300, Ive tried everything i could think of but my car is still in limp mode. Last night it would shut off from low idle but yet start back up and be fine for a few minute. Can anyone offer a solution?

 

Timing belt incorrectly installed or wires not correctly installed

Verify your cam marks line up.

Reinstall the timing belt if marks are off and pray your valves are not bent.
