This answer was rated:

2002 4 runner has dtc 300 and 306. Replacing evap unit helped performance, but some lurch persists.

Ted Ritter :

Hello, welcome to just answer
Those are engine misfire codes, it is specifically a code for the number six cylinder.

Customer:

I guess I wasn't specific enough. How do I diagnose the problem?

Ted Ritter :

Thanks for the reply, please stand by for a moment

Ted Ritter :

This engine uses three coil packs mounted on cylinders 1,3 and 5 on bank one, each coil fires two cylinders, coil #3 is the middle one and it also fires spark plug #6 which is the one nearest the firewall on the other side through the spark plug wire, the first thing to check is the plug wire and the spark plug, do you have a volt/ohm meter available to check the wire, I would also remove the spark plug for inspection.

Customer:

I will check plug and plug wire and respond. Thank you.

Ted Ritter :

You're welcome just let me know if you have any other questions.
