    Thanks HotChevy1965 for your solution. The mechanic checked the code from the computer and it said it was the Mass Airflow Sensor. He checked a price for me at $146, but I went to a junkyard and picked up a used one for $45. I am waiting for him to install it and I will let you know the outcome...

    OK, so it definitely is the Mass Air Flow Sensor..The mechanic installed the used part I bought from a junkyard. It fixed the problem. Inside the MAFS, is a thin copper wire that runs to a switch, it detects air temp and velocity at which it being sucked into the intake manifold and adjusts the rich lean mixture of the fuel that the jets are spewing. In my case (which is usually why this piece fails), the the thin copper wire inside snapped and broke due to age....or it got wet. so it stopped doing its job, but I saved $100 getting the part at the junkyard....Thanks for you help

Sputtering while driving

Have the fault codes read. Replace faulty items. Use only genuine items as replacement as non-genuine are not always compatible with the OEM fitted CPU units I would have the fuel pressure in the manifold tested as well .The engine light is telling you that the CPU has found sensor/s outside set

When I press on the excellarator the truck sputters and sounds like it choking, then after pressing real hard then it moves.

I need more information. Year, make, model, and engine size. Any information would be helpful such as has there been any recent repairs done to the vehicle. Does this happen in park and neutral? Is it specific to cold temperatures, does it only happen at start up and then seem to clear up? Is the check engine light on? Do you have a noticable decrease is MPG? Did it start soon after a fuel tank re-fill? Any and all information would be helpful. The problem you described can be caused by a large number of things. My e-mail is

Focus GRINDING NOISE during excellaration

I had the same exact problem with my 2003 Focus with 108,000 on it. Making right turns and accelerating was even worse. Had many ideas from differant mechanics saying it was wheel bearing, steering rack, loose heat shields, transmission...ect. Well after having wheel bearing replaced and steering rack replaced, the grinding was still there. It was finally discovered that the noise was coming from a bad motor mount on the right side. Had the dealer replace the motor motor mount and finally!!! the problem was solved. Thank God.
