#267660 My car started running pretty sluggish not to long ago....well I was messing around and took out each spark plug wire then put it back while it was running....turns out my middle two cylinders arent firing...any idea what would cause this??? Im thinking head gasket, just welcoming good ideas.

#267666 by not firing do you mean no spark? That's not head gasket related... I'd start by checking your plug wires and spark plugs.
If you suspect a bad head gasket, I would do a compression test and you will know something's up for sure if cyl's 2 & 3 have low psi. :thumb:
