- 2011 Nissan Altima check engine light flashing misfire p0300 p0301 p0302 p0303 p0304. Most common reason for a misfire is a worn spark plug. But a misfire can also be cause by a faulty ignition coil, fuel injector, vacuum leak, emu, wiring or internal engine issues. Let’s check one of those issues.
You got lucky this time.
Hey I changed sparks and coils and had a cylinder 2 mis. I changed them again and got it read a month later as it was still
Driving rough now I have a multiple misfire .. what do you recommend ?
Do you have the fault codes?
@@Jaydiyrepairguythe only code that I have is multiple misfire code
@@emyaburrell1210 I would start by disconnecting the coils one by one with the engine running to see exactly which cylinder is misfire. One faulty cylinder is found check for defective ignition coil, spark plug, fuel injector or low cylinder compression.
But if more than one cylinders are misfiring then I’ll start by checking for vacuum leak or incorrect fuel pressure.
@@Jaydiyrepairguy ok thank you !
P0303 I replaced spark plugz still misfiring same code
Swap the coil to a different cylinder and check if misfire follows. If yes, then you have a faulty ignition coil. If no l, next step will be to check fuel injector and compression
@@Jaydiyrepairguy it was the coil pack boots replaced them & the misfire went away
Hi Jay, SES light came on so Diagnosis by Auto Zone and O’Reiley recommended replacing bank 1 o2 sensor. Replaced upstream o2 sensor twice in the last 3 weeks and the service engine soon light reappears within 5-7 days??
What are your thoughts on that? Thanks!
What codes did you get from Autozone?
Hi Jay, Thank you for responding. The SES light is steady, never flashing. O’Riley & Autozone diag is: P0300
Are you able to do a voice call?
