    Do yourself a BIG favor. Go to Harbor Freight and spend 40 dollars on a code reader. I did and it has saved me a fortune. It will tell you what the problem is in 5 seconds. It plugs into your computer port under your dash usually by the steering wheel. Read the instructions first. The codes are in the book. That problem you have could be anything from a clogged fuel filter to a bad injector.

I have 2000 ford expedition and last few weeks its been making a whistling noise when accelerate, then past few days it's been running rough, idel low and shakes a bit then today check engine ligh


You might check the pulleys that the serpentine belt runs on. Make sure all are free wheeling and not loose or rough or make noise. You would need to remove the belt to check them.

My 1991 Toyota Corolla drives fine and then suddenly it starts to hesitate.


mine did the same thing and it was oxygen sensor
since engine light came on there should be an error code
on computer.Get a diagnostic checker or take to a garage and have them hook uo to the diag connector. I bought a diagnostic checker few years ago and it has come in very handy
sure hope this helps!!

Many people never think about or ask about their exhaust sytems causing problems..a bad catalytic convertor can cacuse exactly what you're talking about..

A very simple check to see if that's your rpoblem
