Hey everyone, long time, how's everyone?

Just seeking some advice/suggestions.

My car for the past 3-4 mths has been running good, once a mth it would bog when hitting the gas but still run (20-30 mins for that one day). Yesterday it was doing the same thing for 1/2 hr but this time it was giving me an engine light, I drove for a few mins, it went away and the car ran OK for the next 20 mins.
This morning, the car is doing the same thing and was running like total **** (a lot worse than yesterday), this time the engine light remained on while I was near my house this time so I pulled over and ran some codes and parked it. Basically it's running on 1 cylinder due to the codes I have received.

I received 5 codes:

P0300 Random/Multiple Cylinder Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P1399 Wait To Start Lamp Circuit

What are your suggestions on troubleshooting this? The motor is up for a tune up right now and I was getting around to doing it in the next couple of weeks but i'm unsure if it will resolve the current issue.

The car is driven like a granny so the motor is not taking a beating..oil level is good.

Any suggestions would be appreciated, thanks

P0300 is because of all of the different cylinders misfiring
It's not only running on one cylinder. It's running like ***. Your plan to tune it up is where you should start. Give it the works. It should clear it up.

Honda does not supply a diagnostic flow chart for this code. P1399 is a random misfire code and Honda/Acura has reported for various models that this could be caused by clogged EGR ports. In addition there is the possibility that the valve cleareance specification may be out of range.

 

thanks a lot

 

Thanks,

I did a tune up..car is running good again..I believe what caused the issue was the rain though..I believe it rained last mth too when it happened.

What causes these issues in the rain?

Thanks

 

How many miles? Sounds like you were in need of new wires/plugs/etc. like I was at 110k mi.
