it was running fine until i got to school idling high (normal in the morning) then the idle dropped and it started running really bad. i parked and got out to look. there was blue smoke coming out of the exhaust and there was a small puddle of gas where it had seemed to have dripped out of the exhaust. how bad is it? what happened? is it going to blow up in the parking lot?

Hey! Its early. You only waited 12 minutes! Any way, give us a few more specifics please. Fuel injection or carbs? Have you tried to restart it? I doubt it will "blow up" but I guess anythings possible. Have you done anything to the car recently?

You have a bad plug wire.
I ordered new ones and they will be here tomorrow. |

Is the CHT lead still connected? Sounds like it came loose. It is the single blk lead that comes off the #3 cyl and has a single spade connector. Any gas leaking in the engine bay? If not, I doubt you have a fire risk but check carefully.

It should be okay to drive it home if you come straight home. If you want, get a ride home and you and I will go get it when I get home tonight.

Cylinder Head Temp lead is fine.
I will show it to you when we replace ignition wires. |

If one spark plug isnt firing, 25% of your fuel gets dumped in the exhaust manifold.

not the spark plug wires but where the wire connects to the plug doesnt look right you can wiggle it with your finger and the car runs the same even when this plug isnt connected. does this mean it is a bad spark plug?

it also seems as if the plug wire doesnt fit on the spark plug itself it comes off very easily, like its not even on.

Sounds like you found it. The wire is threaded into the connector. You can turn the connector clockwise to make a better connection with the wire.
The two need to make a good solid connection, otherwise you won't get good spark on that cylinder ... (IMG:style_emoticons/default/shades.gif) Andy |

When pushed onto the sparkplug end, you should be able to feel it snap over the threads ... Like i said above, make sure the wire is tight where it goes into the plug connector.

Pull another plug wire that seems to be staying in place. Look inside it and you should see the missing clip part. Just don't mix the wires when putting them back on.
