codes are: p0300, p0421, and p0660

p0300- random/multiple cylinder misfire detected
p0421- warm up catalyst below threshold (bank 1)
p0660- intake man tuning control CKT open (bank 1)

That's all the more I can help.

replace: plugs, wires, coils, primary O2 sensor, and a fuel injector cleaner

that should clear the first 2 codes, 3rd honestly I have no idea.

The 3rd code is your VICS solenoid - check to make sure the two small solenoids on top of the intake mani are plugged in - if so, the white one is what the code is being thrown for.

the vics and vcts solenoids are exactly the same. so just get one of those. there probably 80 bucks i believe. i had to do mine as well.

So I just got the same trouble code as he did for the ViCS solenoid. I've been looking online but can't find them. Where can I go to order one?
