I have a 2001 Jeep Grand Cherokee Laredo, straight 6, 4.0L. It's running hard with jerking when pressing the gas, seems okay in neutral. I had it scanned for a code and it came back Cylinder 1 was misfiring. Hubby changed the plugs with no change in how its operating. The 'malfunction indicator light' is still on and blinking. Any clue as to what this may be?? Help!

You probably have a bad wheel sensor. With the ABS light on the computer is detecting a malfunction in that system somewhere. Its usually caused by a faulty acuator pump or wheel sensor. This won't affect your brakes neccesarilly, however, with the ABS light on it means your anti-lock brake system is not functioning. This means if you hit your brakes too hard it will allow your wheels to lock up.
Check the injector for proper voltage. Check the cam sensor,,,,,DO NOT remove it unless you index it to the block. generally, a malfunction of the sensor will affect all cylinders, PS: you did check to make sure there is adequate spark at #1 plug, right?
there are many sensors and and each airbag have sensors so you will have to get it scanned to know where to start. just a note air bag parts can be very expensive so check out your local salvage yard. they can save you hundreds. good luck paul
Yes it can be caused by low quality fuel, and your gas cap not being installed properly. Best bet is the gas cap, so take it off and screw it back on. Then take your vehicle to autozone and hook up diagnostics to clear your MIL.
