    Car lunges at freeway speeds.
    Once I get up to 60-70 mph the car feels like I am letting off the gas and then slamming back down on it and it lunges forward. The longer you drive on the highway the stronger it does it. The mass air flow sensor has been replaced, and a Ford dealership thought it ...

      First step - have the OBD (on-board diagnostic) system checked for any stored fault codes. The issue may be related to the lock-up torque converter or torque converter control solenoid.

      Check the many on-line auto parts sources, such as; or for the replacement parts.

    Can a bad distributor cause the Villager to go into limp mode or fail safe mode?
    We replaced the distributor a year ago and now we are having surging issues.

    Villager is in limp mode. Will not upshift to the higher gears while in drive.
    117000 miles. Check engine light is on. The only code we get is the throttle position sensor which has been replaced three times. We have changed the transmission fluid and filter.

    Car runs 2200 rpm @ 40mph get 13mpg. Then changes on own to 1500rpm @ 40mph. Get 33mpg. Why?
    No a/c being used. No check engine lights.

      The actual mileage is a variable, and will vary based on; driving conditions, road conditions, traffic, engine health (state-of-tune), wind, elevation, road incline, wheel alignment - and other factors. It may be what you are describing is the MPG readout on the instrument panel? If all conditions are OK - no driveability or performance issues - such as no engine warning lights - then this is normal.
      The lower engine RPM at certain speeds is governed by the transmission - whether in overdrive or not. When in overdrive gear, the engine turns over less speed (less RPMs) to increase fuel mileage and decrease engine wear.

      You may try the local auto salvage sources in your area. You may also try the many on-line auto parts sources, such as;, - to name just a couple.

      Here are the Ford part numbers - which one to purchase will depend on the vehicle and application. There was also a recall for the wiring harness - check the AutoMD website for further details for Recall 01V230000 .

    My transmission hose is broken and I need to know where to look to find a diagram to learn how to fix it or chsnge it?

      Need more information - is this the flexible rubber transimission hose, or the rigid transmission line or tubing that is leaking? The repair is similar - only less time and cost with the flexible hose.
      Try the 'How-To-Guides' feature on the AutoMD website - or you may try the repair guides found at this website;

      Thank you for your answer. It is the rubber hose I believe

      Adding brake fluid to the brake master cylinder does not affect the transmission or the shifting. The hydraulic brake system is separate from the transmission.
      Can you provide more specific detail about the issue you are having?

      You may have a bad shift cable or one out of adjustment, in which case the shifter may be in park on the dash, but on the transmission may be in between park and reverse. What you need to do is put it in park, and disconnect the shifter cable at the transmission...see if the linkage on the transmission further moves into the park position. Once adjusted for the correct Park position, then the Neutral position should be OK.

    What is wrong, the odometer goes into a frenzy why driving it fluxuates from driving speed down to zero and back.
    this action continue a few times and stop at zero, however the driving speed does not change. Also if the speed control is engaged the indication light start blinking and it shut off

      Need far more specific info. I cannot know the "piece that needed to be connected" I don't know id you are describing an electrical connector, a hose or what. And prior to you connecting this piece to something there was no issue with shifting. You have provided no detail here. I am still in the dark.
      6/21/2012 Getmoneymadness
      I did some research and the piece that I connected I believe was the brake fluid sensor, I remember before connecting it I wiped off some brake fluid that looked like it was leaking out. Before I connected the piece I never had any problems with shifting. So now I have turn the key to unlock the gear shift, put it in N, then start the car, then I can shift it into D or R. Thanks
