    Thanks.It's been 2and a half years since tune up and 3 since changing plugs,etc.I suspected gas only because other people who have bought gas at this notoriously "cheap" gas station also complained of problems.

    What if they are new plugs, timing belt, water pump, radiator, boots, intake valve, outer belts, and hoses to the radiator?

If the sputter got real bad, I could smell what smelled like weed eater gas inside the cabin. As you could also imagine, there is a loss of power.

the first thing I would start with is looking for vaccume leaks. be sure to check your EGR valve, then move to your MAP sensor. The next thing that it could be is a stopped up catylic converter

2004 grand cherokee 4.0l one day it will run fine the next day it runs rough rich and when i step on the gas the engine cuts out and spits and sputters


When the "spits and sputters" happen are you in low rpm? Can you "by-pass" the sputtering by accelerating? Has your gas mileage suffered?

Replaced battery, plugs, wires, cap, rotor, air filter, fuel filter, added heet water removal and lucas fuel injector. It sputters, backfires/pops when accelerating and it has no power, drives like a golf...


How many miles? I am NOT a mechanic! Sounds like possible timing belt/chain jumped a tooth. Or the timing advance mechanism is malfuctioning. (Unlikely - check distributor is tight or not shifted from normal position too far back or forward.) Assuming belt and not chain, 80 k miles or more, likely need to replace timing belt in any case, before it breaks. If it breaks, you'll be replacing valves and pistons too.

Power fadded over a few days now its dead. Fuel Pump?


It's quite possible to ruin a fuel pump by letting it run dry, especially if it already has years of use. When you first turn on the key, leave the door open and see if you can hear a high pitched whine for about three seconds. That would be the pump priming the system. If you don't hear it, then the pump isn't working. Be sure to turn the key of for about 10 seconds before you try listenng again(it has to reset). It can be hard to hear, especially over the key buzzer.

Sudden loss of power, Backfiring, starts then stalls


Your timing belt could be broken. You want to have this checked as soon as possible to prevent any further engine problems.
