    Yes, It is a Amber color. I will do this and let you know what the trouble code test is.

Is it amber coloured? If it is have Auto Zone, Kragen or any chain parts store run a emission system trouble code test, then post the code back on this thread, let me know.

    Most likely there is either a gas cap that was not properly tightened or one of the O2 sensors is starting to fail.

Would the malfunction indicator light come on if l need a tune up on my 2004 jeep grand cherokee

Tune up would need to be really overdue to the point that something was severely out of range. have a code test done to narrow down the problem area (most larger parts stores do that free) And, if it hasn't been tuned in a million years, it won't hurt to get that done and out of the way as well. (will give you a better baseline for testing)

Malfunctioning Indicator Light still on....

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?

Malfunction indicator not turning off

That was a good idea getting the VAG codes. You should get to a jeep dealer who can analyze the problem.

2004 jeep grand laredo MIL(malfunction indicator light)

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.
