you have multiple misfire po300 and cylinder 5 po305 misfire.the misfire is causing the rough running.The computer has disabled your traction control.You either have carbon in the EGR which simulates a vacuum leak,bad spark plugs,a leaking intake manifold,or low fuel pressure from a bad pump or clogged filter.
i would start with the spark plugs and fuel filter

How to fix diagnostic code for 1999 vw passat po304 po305 po306


Hi. You have misfires on cylinders 4, 5 and 6. If there are no faults on cylinder 1, 2 and 3 then I would check the power to the left bank injectors. Also check spark plugs and ht leads. If there are running issues then this should be an easy fix. If the faults are very intermitant then it can be a bit tricky to isolate.

I have a 1996 crown vic i need to know these touble codes po305 po304


P0304 means that cylinder 4 has a misfire and P0305 is a cylinder 5 misfire. What this means is you may have bad spark plugs, or bad plug wires, or you may need to replace your distributor cap and rotor. I would start with plugs and wires.

Cylinder number 5 is misfiring. Check spark plug, spark plug wire and ignition coil for the number 5 cylinder. The number 5 cylinder is the closest to the front of the car on the drivers side. With engine running in dark (at night) take a spray bottle of water and lightly mist spark plug wires and coil and look for arcing. Autozone will test coil for free.
