I have a 2001 Ford Explorer XLT, stopped at a lite and it died but started right up and hasn't done it again. I havent had a tune up done is awhile. Could this be the problem


Could be a TPMS sensor or a MAP sensor. Check the fuel pressure to why u are at it. Cleanning the throttle body will be helpful also.If its been awhile i would check plug gap. To wide of a gap it wont fire like it should. A fuel filter is a plus also. Might be in the tank?

Engine light coming on and loss of around 30 percent power while driving , engine still sounding great .


When is the last time you had done the service, the oil change, the tuning timing.? If this has not been done for the last several months, I recommend that this be done. Yo can take the vehicle to the dealership for an estimated cost before you decide. If this service is done periodically then you must check your fuel, fuel filters,timing and tuning. Helpful? Good day

02 navigator misfire #7 cyl still after i changed plugs and coil


You've tried everything but getting the timing checked out. You've done all the other parts of a tune-up but that.

When you changed the spark plugs did you notice #7 was especially dirty or greasy, this could point to a seal being broken or a piston ring that needs replacing.

I just changed the oil in my 2002 Impala LS and filled the tires to the proper psi but the message center still reads both messages.....change engine oil..........tire pressure low. What do I need to do to...


ok this can be done 2 different ways 1 , with the radio controls , should be in the owners manual , or the easier way , to reset the oil maintinence light , turn the key to the ON position , engine OFF , depress the gas pedal to the floor 3 times within 5 seconds and it will reset ,

now the tire monitor system , same deal should be in the owners manual , and done with the radio controls , or the easier way , turn key to ON position , engine OFF , cycle the parking lights 3 times within 5 seconds , (turn on - turn off = 1 cycle)

pretty cool huh? but make sure your tires were properly inflated before you reset the tire monitoring system .
