These conditions MUST be ruled out entirely.
Check for any of the following conditions/mechanical problems.
AIR INDUCTION SYSTEM - must be free from leaks
ENGINE VACUUM - must be at least 13 inches in neutral
ENGINE VALVE TIMING - must be within specifications
ENGINE COMPRESSION - must be within specifications
ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks
ENGINE PCV SYSTEM - must flow freely
TORQUE CONVERTER STALL SPEED - must be within specifications
POWER BRAKE BOOSTER - no internal vacuum leaks
FUEL - must be free of contamination
FUEL INJECTOR - plugged or restricted injector; control wire not connected to correct injector.

Unfortunatly, a scan tool will be required to monitor o2 sensor voltages while the engine is running in closed loop. This code you are displaying is NOT an easy solution to trace down. I expect you had an exhaust leak and is why the cats were replaced? Anyway, if so, the PCM can reset the light after a few GOOD trip readings occur that will satisfy the PCM's no fault signal, otherwise the JEEP dealer is going to be your only solution and a pressure test should be performed.

What the P0320 code means. When the P0320 diagnostic trouble code is stored by the Engine Control Module (ECM), it is an indication that there is a malfunction in the ignition/distributor engine speed input circuit.

when you check fuses you must use a continuity tester or a volt meter to verify they are indeed not blown also clean the contacts in the sockets and your turn signal switch may be finished and needs replacement your vehicle is now 17-18 years old by manufacturer date sticker so things fail after almost 20 years there could also be a broken wire on that socket but verify fuses so you can eliminate that cause sometimes they look good but are blown out in the corner at the top ok

Do not think they have any governor in fact that is a big noser .Anyway if you did something like that and be pulled in front of another car or truck or I don't know train and had to bit the gas hard? Now what? Not a good idea, I know Ford and Chrysler have my key that when that key is in ignition will only do 65 or so maybe it's time to change vehicles?

And motor size is? Need more information to help

Jeep Cars &... | Answered on Oct 10, 2019

Sounds to me as if a couple of fuses have blown. There must be a reason why they blew, sometimes is wires grounding or broken wires somewhere under the panel. Better taking it to a professional as could be something simple or something rather complicated. Good luck

There is no "relay" per se for the headlights. The switch doesn't actually switch power to the headlights. It's only a signal to the body control module (BCM). When the BCM receives a signal from the headlight switch, it switches power to the headlights. There is no mechanical relay in this system. Headlight switch is a fairly high failure item on Chrysler products, so the first thing you want to do is use a scan tool to see if the BCM is actually getting the command to turn on the headlights. If it is, then you've either got a bad BCM or a wiring issue from the BCM to the headlights.

It's under the knee blocker panel(comes off w/a couple screws)to your left as you sit in the drivers seat on the '97, wouldn't let put in a link to a image, so I'll just post in the body here,
Go here(may have to swipe your mouse on it and 'copy' link) and take a look at the module and how it mounts.

I suggtes check in the Service Manual, in this link... Secc-7-Cooling-System


If the hoses are news, then its possible that your problem may be in the metallic coupling (lower radiator).

Tell us news.
