Intermittent misses can be caused by bad coils, dirty fuel injectors, and bad o2 sensors, to name a few.

A flashing key symbol normally means an invalid key. Do you have an other key to try? That all the gauges stay at 0 seems to point to a PCI data bus problem. Was the jeep parked outside or at least standing in the rain? Many times water ingress in connector C200 up in the passengers footwell area is the problem. The connector must be removed, cleaned/dried and reconnected. Ofcourse the source of the water ingress must be found, which many times comes from the windshield.

pull the headliner down to access it

You may need to reset the codes. Replacing the sensors may have fixed the problem but the codes will still come up until you tell the ECU that you have. An auto electrician has the correct tool to remedy this.

Hi here is a quick fix for the lifter tapping. Try adding 4 Oz. of tramsmission fluid to the motor oil , and run the engine for two minutes at 1500 RPM. This should quiet the lifter tapping.It works everytime i come across this problem.

The short answer is anywhere above the shield. Look for darker (wet) trails on the front / back of the radiator (where possible) as a sign of a leak origin. Clamps between hoses and radiator openings, thermostat housings, soldered locations such as those around a filler neck, seam, etc. are also candidates for leak locations as well. Inspect the radiator cap too (when cold). Feel along the underside of hoses, support hardware, etc. that slope downward toward the radiator - as coolant may be running along the bottom side of the hose from a different leak origin location. Don't forget that the cooling system is under a small amount of pressure - so a wet spot on the radiator (or anywhere for that matter) could be the result of a stream of coolant that is squirting there - but coming from somewhere else. You could check this after running the engine to normal temperature and shutting it off - then look around for a stream squirting under the hood.

Isuggest that instead of using usual horn system you can try (AH ).NOWADAYS THESE Automotive horns are installed in almost all automobiles, trucks and other automotive vehicles. Automotive horns are intended for use as a warning device to provide warning to other drivers, bicyclists, pedestrians, bystanders, or animals of potential dangerous conditions in the vicinity of the automobile. For example, the horn may be used to warn pedestrians or persons in the path or vicinity of a moving vehicle of the presence or location of the vehicle.
In recent years, it has become increasingly apparent that automotive horns are commonly abused by drivers to show or vent frustration, or to express anger at actions by other drivers or bystanders that are perceived as discourteous. The abuse of the automotive horn by impatient or angry drivers is a common nuisance. Abuse of the automotive horn in this manner may be particularly prevalent in congested traffic conditions, such as in cities or heavily populated suburban areas where traffic is heavy. Nevertheless, abuse of automotive horns has become so common that it is of concern in a wide range of urban, suburban, or rural settings, for example in shopping malls, parking lots, and in the vicinity of sports arenas or recreation centers.
The abuse of automotive horns also raises a number of public safety issues. Abuse of automotive horns is associated with the increasing problem of "road rage," a condition caused by driver frustration. Under these circumstances, the abuse of the automotive horn may provoke a violent response by a nearby driver.
The abuse of automotive horns in the manner herein described is characterized by a length and repetition of horn use that is unnecessary when the horn is properly used, leads to annoyance to other drivers and non-drivers, and also increases the general level of "noise pollution

Hope helps (remember rated this).

The camshaft position sensor is located inside the distributor. It is a hall effect swich, simply remove the distributor cap and the rotor and you can lift it out, unplug and replace.
Have fun but beware a bad crankshaft position sensor can cause a false cam sensor code to be set sometimes.
Good luck.

Gas in the oil is serious. Do not drive it. Have it towed to a reliable repair place. Driving it even short distance could result in increased damage.
