    have u checked the fuel pressure? should be 44 PSI under a load, have u changed the fuel filter every 60,00 miles as Ford recommends? Also get some MAF cleaner and spray out the inside of the MAF sensor.

Check your spark plug wires. At night, or in a darkened garage, start the engine and look for sparks between the wires and the engine or anywhere else. Shut off the engine, wipe the wires off and retry. If the wires are sparking anywhere, the insulation is shot and they need replaced.

My gears are P- park R- reverse D- drive (2 Drives one with a box or circle around it) what is each D for


  • D with no circle is just "Drive." this a lower geared drive and best used around time as it provides a better pick up and over all response.
  • OD is "Over Drive" and used for cruising speeds ove 50+ MPH down the highway. Over Drive allows the vehicle to cruise at a more sustained speed with less engine speed and provides better fuel consumption.
  • While you are in Drive going down the highway and your speed reaches 50 MPH just switch gears into Over Drive and you will notice your car "relax" a bit. Remember you don't want to switch from Over Drive to Drive until you get down to around 45MPH or it can be a little rough on your engine and transmission.

  • Hope this helps and thank you for using FixYa.

We have had the car for only 4 weeks, and the gas engine now keeps coming on at very low speeds. The electric battery keeps switching to gas at any speed. Prior to this problem we were reaching speeds of...


I'm pretty sure that 4 weeks is within the the warranty period... If you think something is wrong with the battery power system don't hesitate to bring it in to your dealer. If you want to make sure they aren't BS-ing you, find an independent mechanic who works on hybrids, spend a little money, and have him just give it a preliminary look (no actual repairs) and ask him your questions once he sees the car. Then take that information to your dealer if he thinks something is wrong, so you'll have independent proof that there is an issue and they won't give you the "don't worry about it" run-around they do.\

Maybe you've been running at low speeds much more often and the battery has been running that whole time. When that happens the gas engine engages at lower speeds to take over for the battery as it charges. I would need to know more about your driving habits to assess the problem fully. Do you drive city miles a lot? Highway miles? about how many of each and how much time between the two?

Engine misses/hesitates on low speeds. Runs fine


is the check engine light on? have you ever serviced the injectors? if not try that first because there are many things that give the symptoms you spoke of. but this is the cheapest.

Pickup hesitates when strarting off, has a miss while driving at constant speed. If it were and 50 or 60 model I would think the timing was off.


Check the gap on your spark plugs and also check the resistance of the wires - a low resistant wire will do this at take off and around 40 mph

Whats the average gas mileage


Well gas mileage depends on alot of things first do you have the very common 350 cid small block or the 454 cid big block,2nd Do you drive like around the speed limit or do you go way faster?3rd Do you do mostly highway or in town driving?4th Is it 2wheel drive or 4 wheel drive?Well your average around town for the 350cid motor around town would be about 15 and on the highway 18. If you have the 454cid you would get about 11 around town and about 15 on the highway these figures are also figuring in that the vehicle is tuned up properly.

When you try to give it more gas at 50 mph, it starts to hesitate


It sounds as though your engine timing is off. Engine timing changes with engine speed. It is possible to adjust it yourself if you have the knowledge.

Hesitation at 40mph and 50 mph.


A pop and hesitation is likely a backfire. The hesitation around 40 and 50 would be in keeping with that theory. There are several reasons you might be getting backfires and hesitation. If your ECM is adjusting the engine to run too rich this could happen. Misfiring might be occuring. Timing could be out. But one of the most likely is a restricted exhaust, likely due to a plugged, damaged or worn out catalytic converter. In some cases the converter may be bad enough to be giving you some performance problems, but not yet quite bad enough to signal an error. A vacuum test can help confirm whether this is exhaust related.

Vehicle missing at highway speeds


You really need to hook up your vehicle to a computer or scanner to check for codes. You may have faulty plugs & or wires, How is your fuel pressure? When is the last time that you changed your fuel filter? Is your touque converter lockup in your transmission slipping in & out ? All of these inquirees need to be checked, It is very hard to help without having your car to diagnose. i need more info...
