P0301 - OBD-II Trouble Code - RepairPal

is it a po300 random/multiple misfire! A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked/leaking EGR valve / passages Faulty camshaft position sensor Defective computer. if no symptoms reset check engine light, and see if it comes back on. but first check for a vacuum leak in a hose or around intake manifold.

check compression, fuel pressure

Sounds to me like a loose wiring connection behind the dash or possibly loose fuse connections

any time you have a random misfire the light will flash untill misfire stops. if light is just coming on like a flicker you may have a short in dash or mill light circuit.

well... the misfire codes are logged in when its running bad, but first I would want to verify fuel pressure when its running bad.

SOUNDS LIKE IT COULD BE A BAD CONNECTION AT THE BATTERY. IF THE TERMINALS ARE LOOSE OR CORRODED THEY CAN DISPLAY SOME OF THESE SYMPTOMS. IF THEY ARE TIGHT AND CORROSION FREE, THEN HAVE THE BATTERY CHECKED FOR VOLTAGE AND COLD CRANK AMPERAGE AT YOUR LOCAL AUTO PARTS STORE. MOST AUTO PARTS PLACES CHECK THIS FOR FREE. BUT DON'T RULE OUT A BAD BATTERY CABLE. THANKS FOR USING FIX-YA. PLEASE KEEP ME POSTED. GOOD LUCK

A misfire on this type of vehicle can be due to 2 factors if it missing spark it will trigger a misfire code and it you have a bad INJECTOR. Most misfires are due to missing spark but there are quite a few in my experience that were due to bad injectors or bad injector wiring. To check this you need a NOID light disconnect injector wire on suspected cylinder in your case #1 and connect wire to NOID light (engine must be running for this) Your NOID light should have a consistent flickering light going while vehicle runs at idle. If light its NOT flickering at a steady pace and flickers erratically. THE PROBLEM IS A BAD Injector wiring or a bad computer. If light flickers consistently and in a steady pattern then YOU HAVE A BAD INJECTOR. Replace injector and that will solve this problem. I know this is a lot of info but It will help you alot. Good luck and thanks for using FIX YA
