Fuel is metered based on a signal the computer gets from the coolant temperature sensor. Over heating may have damaged it. If the wire connection is good the sensor may be bad, Change the sensor. It is very close to the thermostat (19MM deep well socket needed)

Get a Hanes manual for your vehicle from PepBoys and it will tell you all you want to know.

That shouldn't have anything to do with the dragging you need to take your starter off and get it checked

ok on todays automobiles the gas cap does more than just seal the gas tank. Now they run a return line to the tank. this does 2 things. it returns un used fuel and vapors back to the tank , and it pressurizes the tank to help improve the fuel pump. Now as it is possible running without the gas cap may cause problems I am not 100 % positive that is your only problem.It sound like the knock sensor is detecting the knock you mentioned and is trying to retard the timing to fix it . In doing so it has retarded it to far causing the engine to loose power and eventually stall. I would first replace the gas cap. then run a good gas additive to a full tank of gas to clean out any water and dirt that may have gotten into the tank while the cap was off. now the issue of the knock as you described. is it a knock or a ping? A knocking sound is loud metallic hammering noise. a ping is a ting not very loud. if it is a loud metallic sound I would have a reputable mechanic check it soon, as it could be a serious issue. Ping can be caused by bad or weak gas or cheap low octane gas. I would run a mid grade gas in it and see if it fixed the issue.

They're all on the exhaust system. Just trace them from the exhaust manifold down the pipe to about the middle of the car. My van has 3 of these.

you might have air in the cooling system, or water pump might not be functioning right, I would try burping the system first too see. with the car off and cooled down pull the radiator cap off and start the car, let it run for about 30 minutes should force all air out of the system, keep a eye on the coolant level while doing this.

don't know if you can but you can try resetting everything. you disconnect your battery for 10 mins (positive post on battery) then reconnect it then start your car.

you've soaked the electronics , spray a water dispersant on to every wire connector and component you can see WD 40 is a good choice , you may even have to unplu the connectors to get the contacts dry , pressure washing an engine is never a good idea without trying to protect the electronics , pay particular attention to the throttle body area , yuo may even have to remove the air intake to get to the TPS etc , paitence is the way to resolve this issue

In short you can't on this make and model year.

Catalylic converter heat shield rattle?

If you replace the timing belt, you line up the marks. There is no special timing. all you do is make sure cylinder one is Top Dead Center then install timing belt

ok first check cable to transmission to make sure it is properly adjusted, Does it lock into park ? (ie does the parking cog engage and hold the car from moving) If the park cog does engage the I suggest rebuilding the transmission as the band inside the transmission may be worn and welded to the drum.

where is this f....fuse?

headlight fuses are out under the hood. check to see if they are good. some have a relay they will go bad. they should be marked to indicate what they are

Check the main fuse. It's typically a 80 to 120 amp fuse. It's also typically the largest one in the fuse box. It won't look like a normal fuse and also may bolt into the fuse box. Disconnect the battery before checking anything in the fuse box. If the fuse is good reconnect the battery cables and make sure everything is tight .

There is not an inertia/fuel cut-off switch on your car.

check your coils, plugs & wires and fuel filter. if all are good check the fuel pump pressure
