I still have some problems, the car is driveable now...but I have a bad low RPM miss, with a big power loss. Pulled all plugs and wires and they check out fine, I'm stumped.

 

I'm having the same problem right now after my header install. My car has 85k miles on it and I don't think the plugs had ever been changed (I bought it 3k miles ago) so I think I have a cracked plug wire. I've got some new wires coming that should be here tomorrow and I will post up once I get them on.

 

Do plugs at the same time sport

 

I would if I didn't just change them a week ago when I did the headers.

 

In that case, new wires should fix you right up.

 

Just an update, all plugs and wires 'looked' fine, but I replaced them anyway and my miss went a way. So strange, plugs and wires looked practically new.

 

At least its fixed now. You never know if one of your plugs has a hairline crack in the porcelin or one of your boots isn't seating completely unless you have the help of a scanner to isolate which cylinder(s) is causing trouble.
