2003 acura tl error codes po301 po302 po304 po306 p1399 po300


PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

Multiple engine codes PO300, PO303, PO306. what is going bad on this 2005 kia sorento?


I've had similar issues. The fix I used was to take my vehicle to AAMCO and let them run a diagnostic check. Most often it will be at little or no cost and, if you don't want to mess with the fix anymore, they can fix it onsite.

What is Diagnostic code PO306 and PO118


Code 306 is a miss on cylinder 6, and code 118 is for a short to ground for the coolant temp sensor.
Once the sensor is replaced or the problem fixed, you would need to clear the code with a scanner. Same thing for code 306.

2002 Lincoln LS, Enigine has bad miss. Trouble codes are po171b, po174b, po300b, po305b, po306, po420, p1131


Fix the misfire concern on cylinders 5 and 6. That will probably take care of the lean codes p0171 and p0174. The catalytic converter is probably damaged from the misfire concern....that's what is setting the p0420 code. Take care of these concerns first before fixing p1131 code

TROUBLE CODES PO301 & PO306 HAVE ALREADY


P0301 = Cyl no 1
P0306 = Cyl no 6

If you have changed plugs and leads and confident that they are now ok you need to run a compression check on all the cylinders, I'd emagine they should all be running at approximately 150psi per bore, if 1 & 6 are down it could be the head gasket, timing or piston rings.
