code p 0443 refers to evaporative emission (EVAP) canister purge valve ---circuit malfunction====causes ---wiring--- EVAP canister purge valve ---ECM
code p0308 refers to cylinder 8 ---misfire detected ====causes ---engine mechanical fault ---wiring----ignition/ fuel system--- injector---ECT/MAF sensor---ECM
I am thinking here that it restarts , not after cooling , but after the vacuum in the fuel tank has lessened and allowed fuel to be pumped to the injectors and the fuel pressure is re-established
if that is the case then a weak injector or partially blocked injector will misfire under those conditions
I would fix the purge valve so that the tank vents properly and the rest may go away

Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

Check your spark plug, wires, distributor cap and finger. If you spark plugs older than 15000ml, replace them. To check your spark plug wires, use a tester (U can buy at any auto store) you hold direct on the wire and a small sparkling will show you if the wire works or not. You can check the wires also with this: use a single spark plug (don't remove one out your engine!), remove the wire from first SP, connect it with the single SP, hold it to ground, let someone start your engine...you need to see regular sparks.. do this step by step with all 6 wires. If all wires are fine, check the SP's, If you miss on one wire, replace the wire, if you miss on more than one, chekc the distributor cap and finger. If this items are older than 20000ml or 5 years, replace them.

hi
your blend doors are damaged or broken, go to heatertreater.net they have a quick fix blend door repair kit that you can install yourself in around half an hour, this really works as i have fitted a few myself. jeep will quote you around £800 to fix.
hope this helps

Its related to the oxygen sensor and/or oxygen sensor heater. There are 4 sensors the Jeep is equipped with.

In most cases one of the recommended solution for all those faults is a sensor replacement, however before doing that and spending a lot of money. Go to auto zone and have them tell you what O2 sensor is bad buy it and replace it. Go back to them to have the code cleared. O2 sensors run 20-50bucks. Good Luck

Sensor #1 is the sensor before the converter (upstream sensor)

code po720 is the output speed sensor malfunction
