Thanks Prof!
Bad news though. I did get to drive Ms. Libby today, but it was just a short 6 miles around a large hilly block. It threw a code when I was about 100 yards from the shop. I coasted in and parked her. The mechanic came out and put the scanner on and read P0303. Which he said is a general code for misfire on cyl #3. He said he would replace the spark plugs, because they sent him Champion plugs, but he doesn't really like Champions, so he will get NGK or similar. I told him I had just replaced the plugs before the engine blew. Maybe they have about 5-6 miles on the plugs right now. He said he would use them then. Then we opened the hood. There was a fine mist of liquid on the driver side firewall. It was very wet. He got to looking and found that the neck of the plastic radiator has a tiny hole in it. He put some sideways pressure on the neck and it sprayed out. He said it can't be repaired, so they will be putting in a new radiator too. Ed the mechanic said I could have her back tomorrow around noon.
Is there anything else that could throw a P0303 code? Are plugs the most likely culprit?
