P0301 Code - after spark plug tube replacement
 
Yesterday I replaced the Spark plug tubes on the right side of the engine.

After that the check engine light started flashing and it is running rough.

I bought a Actron 9125 code reader and I got the following (I may be giving superfluous info)

P0301 misfire
5INC
Mil On
Monitors
02 Sensor
O2 Heat
Catal
Evap
Sec Air
3 Ready
Misfire
Fuel Comp

I think the pertinent message is the P0301 misfire code.

I don't even know which is "cylinder one" - could it be the front right cylinder?

I do not think I damaged the coil, but it may not have plugged back on to the spark plug well. I do know that the connector came off on the front right coil so perhaps I didn't get it plugged back in correctly.

Also, I broke in half the top AOS tube (duct taped it so I could test run it) and wonder if that could have something to do with this.

Any recommendations are welcome!

Thanks.

Check the plugs are all seated tightly into the coil packs. Did you look at the coil pack when you had them out. There is a tendency for them to crack and ground out. It produces a week spark.

I had the same error code when I did my plugs and tubes.

My problem was that the connector wire to the coil packs were not tight. I had to make sure each of them "snapped in".

See the attached pic of the cylinders. Looks like it's the one closest to the passenger door.

I was told this on one of my recent threads - By Jager. Which one is it then?????

2-4-6 on the left (US driver's side) 1-3-5 on the right (US passenger side).

I'm having problems after my tube/spark plug change last night. I'll have to keep an eye on this one. Mine mainly just smokes - no codes yet, but I've never let it warm up.

I had similar problem but it was quite simple, I didn't fully push in the wire plug.

I reseated everything and mine is back to normal (or much better since the old plugs were fouled)...yay. Hope you get yours fixed quickly. I just did everything over again.

Did you figure it out? I can look it up in my book upstairs if you are still uncertain.
