P0304 any help

[rodkil1]

Ok I know is a #4 misfire.
I've changed my plug wires to a set of MSD's from Modern Performance and reset the ECU. The Car only has 4500 miles on it and I have to get it smoged( I bought it in Vegas and to register it in cali I have to smog it.) by the end of the month. The dealer can't get my car in until the end of the week. Any help would be great. Thanks in advance.

Bump ....... Any Help Please... I was thinkig maybe the spark plug wa s fouled but I have not checked yet.

Check to make sure the plug is not fouled... When you pull the plug make sure it is gapped properly. If that is ok check the coild pack with a volt meter to make sure it is not defective.

swap the spark plug #3 spark plug to the #4 and vice versa? if it truly is the #4 spark plug it'll now give you a #3 spark plug error code now right?

Thanks guys I will try that in the morning.

How would I test the coil pack? I'm only used to working on old cars.

[DOMEIMAZN]
