Unhook your battery (neg terminal), let it sit for ten minutes, then start the car and let it run for two minutes without touching anything. This resets the computer, I had a Buick that required this about three times a year, fixed it every time. If this isn't your problem, is is getting progressively worse? Look at the coil, it may need to be replaced. Of course, make sure your air cleaner is clean. Do you have any codes in your computer? Go to one of the discount auto parts stores they will read it for free. Of all the sensors, it may be the mass airflow sensor, look atr this link, it is located in air delivery system connected to your air cleaner housing. If you pull it out DON'T BREAK THE WIRES IN IT, but you can sometimes clean them with denatured alcohol and a Q-tip.

I have a 1998 f150 truck with a 4.6L engine, starts fine but looses power when I put it in gear.


Sounds like a Fuel problem to me. Seems there is enough fuel to start and idle, but once the engine is placed under a load, it loses power due to a loss of fuel.
I would have the Fuel filter changed first and if the problem continues after that, I would have the fuel system tested to insure the proper pressure. The Fuel pump is in the Fuel Tank, so this can get to be a time consuming, and thus expensive operation if done at a dealership or reputable shop.
You might also check you air filter. There are only 3 things one needs to have a good running engine:
1)Proper Air Mix
2)Proper Fuel Mix
3)Proper Voltage
If any one of these are missing, it causes a problem

No one can guess from afar

You need to have the vehicle to run
some tests

Worn out Battery or Run Down
Bad Starter Solenoid
Bad Starter

Gas doesn't freeze.

You know how to fix it
You have a local repair shop
pick it up,diagnose and repair

I am having ongoing problems with the truck miss firing and rough running. Timing is ok, replaced cap and rotor,coil. It still starts rough,idles rough and misses when at cruising speed,although it seems...


Misfire is a common driveability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle. The engine also may be hard to start and may even stall at idle, depending on the accessory load (air conditioning, headlights and electric rear defroster, for example).

When misfire occurs, performance suffers along with fuel economy, emissions and idle quality. And, when a misfiring vehicle is subjected to an emissions test, it will usually fail because of the unusually high levels of hydrocarbons (HC) in the exhaust.

What causes a cylinder to misfire? Basically, it's one of three things: loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad spark plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.

"Lean misfire" can occur when the air/fuel mixture is too lean (not enough gasoline in the mixture) to burn. This can be caused by a dirty, clogged or inoperative fuel injector; air leaks; or low fuel pressure because of a weak pump, restricted filter or leaky pressure regulator. Low fuel pressure would affect all cylinders rather than an individual cylinder, as would most air leaks. A leaky EGR valve can also have the same effect as an air leak.

Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited. The most likely causes here are a leaky (burned) exhaust valve or a blown head gasket. If two adjacent cylinders are misfiring, it's likely the head gasket between them has failed. Also, if an engine is overheating or losing coolant, it's likely the head gasket is the culprit.

Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load or operating conditions. They seem to occur for no apparent reason. The engine may only misfire and run rough when cold but then smooth out as it warms up. Or, it may start and idle fine but then misfire or hesitate when it comes under load. Also, it may run fine most of the time but suddenly misfire or cut out for no apparent reason. Intermittent misfires can be a real challenge to diagnose, so let's start with a steady misfire in one cylinder before moving on to intermittent misfires.

Hope this help.

The problem is due to a lack of compression in the engine when the truck is cold, try using the engine block heater more, or allow more time for the truck to warm up.
