Google Your CodesThen you will know the systemwith the failure

lost of reasons but most likly it a o2 sensor

This happens because of the difference of temperture between the hot engine exhaust and cooler outside tempertures. Its why you see exhaust during colder outside tempertures.

change the rotor and place a new distributor cap and along with changing spark plug and wires if not check for timing

Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

Check everything in that right front driveline. Could have a problem that when the four wheel drive puts some tension on it, it stops making noise.

This would your transfer cause mod under dash or your t/case motor is bad

Its your No. 6 Injector. I had the same problem on my 97 Jimmy. Replaced the SPYDER injectors and it runs fine now.

You cannot, see other post.

You cannot do that because the sensor has a varied voltage output and the ECM will see it as something wrong.

po171 fuel injection system to lean bank 1 po174 same thing but bank 2 that could be the oxygen sensors

Here's a link to location,here's the part.

There is a headlight relay on 1998 models, but not 1997.And if you have daytime running lights there is a relay for that.But none of that would affect the dash lights.So my vote is for the problem being in the actual headlight switch, or a wiring connection. The headlights, parking lights, and dash lights are all on different circuits and fuses. But they all go thru the switch.

some times a bad water will make noises. most of the time a bad water pump will leak water ,and cause the engine to over heat

your fuel pump sending unit is bad ! in the tank !

Have you checked the blower motor for power and ground ?Is the resistor ok ?And did you get the fuel line problem fixed ?

Starter relay is in the middle of the firewall near the top of the firewall. I would check connections and /or replace that relay. They are very inexpensive.
Also, you could turn the key on and run a jumper wire from power to the starter solenoid and see if it starts. You can easily get to the solenoid though the right wheel well. Be careful not to ground the wire by mistake.

sounds like it replace this..

DISTRIBUTOR MAY BE GOING OUT OR JUMP COIL

Yes there should be a fuse box near the battery.
