Was pulling some great runs on the 125 shot, 11.7, 11.8 and then 11.6. On the third qaulifying run...12.0. WTF! Turned down the run off to get the slip, the car was running a little off. Half hobbled it back to the pits, opened the hood, started pulling plugs and then noticed the line off the fuel pressure regulator. Oh ****, pulled all the plugs, some scorched, some almost looking dark, possibly fouled. Pulled the distributor cap off, all contacts were gunked up, almost no copper even showing on some. I then checked oil and coolant for possible blown head gasket. Everything looked fine there. Started the car back up after connecting the hose and idles fine but rough, give it gas, it goes up the RPM range but stumbles a little all the way up.
What do you think happened? I'm getting a new cap, rotor and plugs tomorrow morning. Do you think when the fuel line came off I was running to rich/lean and screwed up the ignition system (rotor, cap, plugs), or did I melt a piston or two? Any input would be much appreciated. My link in my signature has all the crap on the car. I'll post my new best time slip shortly. Basically, an 11.6 at 120 mph. I also had 4* timing out, normally at 16* advance, so basically 12* advance on the 125 shot. I didn't feel like I was taking the motor to the max, and felt I was being conservative/safe.
Thanks guys.
