I have a 1999 Jeep Grand Cherokee limited,V8 Quadra-trac which dies on the road; dash gauges drop; "no key" lite displays on dash. Restarts after cools. Two codes P 0443 and 0308 are showing? help


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

Remove front Rotors


To remove the front rotors,you first need to support the vehicle with a jack stand.Then remove the wheel.
Once the wheel is out of the way you need to take the two bolts off of the backside of the caliper, then compress the caliper and lift it off of the rotor.
Now you should be able to easily remove the rotor from the Jeep.

95 jeep grand charokee laredo hard to start,


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.

Error code P 0161 for 2000 Grand Cherokee Limited V8


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
