How To Diagnose & Repair Engine Misfire: OBD-2 Code: P0306, P1399, P0300, P0305, P0304, P0303, P0302

[@begood82]

Do I have to disconnect the battery terminals? Thank you, sir!

i've got a 99 acura cl 3.0 and it misfires on 4 cylinders changed all of the plugs and now 2 are misfiring. it doesn't have coils but distributor wires. could the wires be at fault?

[@chrislecompte5964]

Was the bad coil from cylinder 6? Not a real important issue but it was interesting that your OBD tool listed cylinder 6 first. Code 306.

[@HaynesManuals]

Sure was! The only coil that had an issue was #6. When we unplugged the coil while the engine was running nothing happened. The engine did not bog down. If it bogs/sputters it means it stopped firing. Yes, it was surprising that it threw a code for all cylinders instead of just the one. But you should just change them all anyways. The coils come in a set at the store anyways.

Thank you for the Excellent Video. Would you kindly share the name of Scanner to check Misfiring Spark Plugs for home use? Thanks.

Could it be possible for it to misfire for using 91 octane instead of 87? i drive a 98’ Honda Civic EX

Nice video similar engine to the Odyssey only difference is the liter of displacement of the engine

[@HaynesManuals]

Thanks! Honda/Acura really makes cars that last!

@@HaynesManuals Thank you very much regards

Thanks. Good video. Need to do videos on the rarest suv in America. The Isuzu Axiom. I am having a p0160 code. I checked all the usual suspects, broken wires, leaky exhaust, bad O2 sensor. Need to find all groundings on system so I can check those. A video on the Isuzu axiom grounding placements would certainly help.

[@HaynesManuals]

Thanks for the suggestion! We'll definitely try to get a video on grounding issues.
