Ya I had to learn the hard way what spark blowout was lol.
X2 First do new plugs gapped properly, if that doesn't help replace the wires. It's unlikely for the cat to cause symptoms like this but it's not unheard of. If you think your cat is the problem you could scan the car to see if you are boost stacking from the clogged cat.Like I said, new plugs and wires - plugs gapped properly. Has anyone replaced the cat converter and found this to be the real problem?
