number 4 misfire check either plug or coil --as to jerking if vehicle is not running correct [misfire ]it will not drive smooth trac light --it can be related to the misfire or check abs and brakes and power braking will set off traction control and puts a strain on brakes and c/v axles
Debbie, code p0300 is a random misfire code,
- bad spark plug (s)
- bad ignition coil (s)
- plugged or faulty fuel injector (s)
- Intake leak
- injectors harness is open or shorted
- Injectors circuit has poor electrical connection
- Ignition coils harness is open or shorted
- Ignition coils circuit poor electrical connection
- Insufficient cylinders compression
- weak fuel pressure
see links below,
PO302 misfire # 2 cyclinder, PO241,boost pressure circuit low, PO442 evap has small leak, The misfire is the code you need to verify first, if you want to fix it yourself your best bet is to replace the sparkplug and inspect the soil boot for and burn through marks(whitish)then take the #2 COP and swap it with another COP and see if the misfire moves if the misfire moves replace the COP,as for the PO442 tighten or replace the gas cap
A flashing check engine light indicates a misfire that has the potential to damage your catalytic converter.
I would start by inspecting the area where the ignition wires plug onto the ignition coils. Any burnt coils towers or ignition wires indicate the need for replacement. Your misfire issue regardless of the cause, needs to be repaired before your converter is ruined. Good luck.
very common problem two things either the injector on that cylinder is bad or the fuel rail need clean out with injection clean a good shop can clean them.
