I have a 1998 Acura 3.2 TL that is misfiring on the #2 cylinder. How do I replace it and where is it?

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.

Do a cylinder leak down test,for bad valves on #3
or head gasket,misfires for a reason

(Cam Worn ?)

Have to get rid of any misfires

If your taking out 20% your correcting for a rich condition,maybe

Some injector issues,old,need to be sent away for cleaning & flow
testing or replaced?

Drive it for 30 miles & add short & long term & see what you get

Exhaust Converter any good ?

check that the HT leads are separated and not touching each other. The misfire may be simply the spark being inducted into the plug with the least resistance and is random and that is what is setting off the light.

check spark plug gap and coil, also note any other abnormalities in engine performance, cylinder compression?

Misfire in cylinders 1 and 5

Or just spark plugs or wires. Or Distributor/ignition. check the cheap things first. Also, replace your fuel filter.

the P0301 means Cylinder 1 Misfire Detected, and the P0303 means Cylinder 3 Misfire Detected. I think have known how to fix the problems after you knew where is the problem.

On most Honda's when you get a misfire happening across the whole engine like that there are a few likely issues. the ignition coil if it's a single coil style or the connector at the distributor. They also have some issues with EGR's and plugged ports which can mess with the fuel trim numbers. It's important to check the fuel pressure and if possible a timing offset spec from the scanner whenever you're dealing with misfires on any vehicles Honda or not and determine correct pressure and flow whenever possible.


Hope this helps.

CODE P1205 - CYLINDER 5 MISFIRE DETECTED.POSSIBLE CAUSE BAD COIL + SPARK PLUG OR BAD PLUG WIRE- DIRTY CLOGGED FUEL INJECTOR .OR INTAKE OR EXHAUST LEAK TO THAT CYLINDER.IF ALL IS GOOD DO A COMPRESSION TEST ON THAT CYLINDER.

remove the valve covers and check the spark plug seals .. maybe theyre old and brittle and need replacement.. maybe arent sealing well and allowing oil down to the plug
