Check to see if mice chewed up cables and rats nests or corroded wires. This would cause a ground, and happened in my car before. Check to make sure your PCM is getting constant voltage and enough amps. check your fuses and relays. Change your gas for sure, you probly still have winterblend gas in there.

the code you have is because you have a misfire on cylinder number 5 since you have already changed all the plugs and wires only two other possible causes either injector number five or a bad valve on that cylinder while idling put a piece of paper at the tail pipe if paper gets sucked back against pipe its a bad valve if not i would go after the injector..good luck hope this helps you.

sounds like it mite be your thermostat sticking needs to be replaced

Have you replaced the fuel filter and tested the pressure from the fuel pump? It sounds like a fuel flow problem and those are the two most common problems.

Try jumping the starter i.e use a starter manual switch. If it cranks than most probably you have a faulty switch.

It's possible you have a faulty fuel injector at that cylinder. You can always check the resistance on that fuel injector and compare it to the others to see if they are about the same. That's where I would go next. I hope this helps and good luck.

Troubleshoot your radiator fans. Could be the main one failed. The AC booster would have a hard time keeping engine and AC cool for more than a few mins.
Check the under hood electrical box. Fuse, relay. Possible the fan motor itself. Unplug it at the wire connector and jump 12 volts to it. No go, replace fan motor.

check fuse and voltage at the fuse and also check voltage at side marker with multi-meter. probable that fuse is blown. if not is it just rears/just fronts or just right or left ones.

Your best bet is to head to a advanced auto parts/napa/or pepboys and have them check it first and go from there, it is free, if you bring it to a garage most places will charge you 80 dollars just to do that.
