White smoke, very bad fuel loss, stalls when trying to idle
Jeep cherokee. Ran with no white smoke and was good on gas usage, though you could feel slight hesitant on gear shifts..
What happened is one day it didnt want to start, acted as if the battery died over night. I tried to jump start it. Found out he battery is fine, but it will not turn over as if not recieving gas. Took it in to get fixed.. A day later with a 340.00 bill, the truck starts now but with these symptoms that were not there prior before taking it in (white smoke, burns gas like hell, stalls when idle have to keep foot on the gas peddle, and now two missfire spark plugs perhaps)

Check the fuel filter, then, if you feel like it's a problem with fuel. It sounds to me, though, like it's probably the EGR (this regulates how the leftover gas vapor gets re-introduced into the gas mix). Check the air filter while you're at it. You might also end up replacing the mass airflow sensor.
It appears that the fuel pump might be going bad. To eliminate this possible cause, have the pump output pressure tested by a mechanic. It is located in the tank. The pressure test can be done in about 1/2 hour at a good garage.The fuel pump replacement, a four hour job, costs ~$500.00.
check the O2 sensors in the exhaust manifold with a automotive meter not a code reader ,then trade it in for a diesel manual version as these are impressive but 4.7 litre gas guzler at our petrol prices about 10 dollars a gallon in the -uk and around 7/8 dollars here in spain this vehicle you couldnt give away here
hello, it sounds like the ECT (engine coolant temperature sensor) is failing, the sensor communicates with your computer and has affect on fuel usage, it is common for bad sensor to allow too much fuel and cause cylinder flooding, this in turn will lower cylinder compression and cause miss, black smoke, check engine lights, easy too overlook without propper diagnostic equipment, easy too change and fairly cheap! good luck, marty
Your Jeep is Burning Oil. Do you need a Quart every Now and Then? The only way to fix this is to get the Piston Rings Replaced and is not Cheap. There are a Few Additives on the Market that you can put in the Motor to Minimise the Problem for a While. You need to go to Your Auto Parts Store and see what is available in your Area on these though. Please Rate My Response! Thanks!
The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.
Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?
This seems almost text book to me... I would have someone local to you to have a look at it to be sure.
