Mine does the same thing(same year) and my best guess is....
It only seems to do it when its really low on gas. On the expedition the pump is located near the back of the gas tank(when backed into a driveway the gas gauge reads significantly less gas than what is really in there) so when accelerating the gas sloshes around and the pump doesnt get enough gas to keep it running. Hope this helps.

1997 opel corsa 14i while drive if I depress accelerator car backfires,how do I fix that

Tune it up. New spark plugs if they are over 50,000 miles old.

Backfiring is typically a symptom that occurs with a gasoline engine that has spark plug wires crossed, spark cross firing inside the distributor cap in dust or condensation or an over lean condition.

If it runs smoothly when normal cruise it wouldn't be crossed wires so that leaves an over lean condition or cross firing in the distributor cap as the most likely causes. So check the inside of the distributor cap for moisture, dust etc and clean it if you find it.

Next, to check for over lean on acceleration the most likely is partially plugged fuel filter so renew it. Next step is to clean the fuel injector (s) with the good breed of fuel injector cleaner that you add to the fuel.

Backfires during exceleration

Tune up time or bad gas. If it's been awhile since you replaced the plugs, check them. You may also want to try adding a higher grade of gas or a bottle of octane booster.

Hesitation and backfire during exceleration

Did you recently replace your plugs or wires? Sounds like you have a wire crossed. If not, it may be time to replace the plugs (tune up). Also check your fuel filter. It may be clogged.

Why would a VW air cooled engine backfire while idling.

Check the point gap, file ,clean and adjust.Point/ condenser, New cap and rotor, wires and plugs , all for good spark. Unburnt fuel igniting is a backfire, Tune up vehicle and if that doesn't work, then you need to check valve lash.

Exhaust decel popping

Or maybe too much fuel-backfiring in the exhaust is the burning of the unburnt fuel in the exhaust. Check the fuel pressure. You can rent fuel pressure gauges at autozone, I believe. If too low, possibly a bad filter or bad pump. If too high, test the fuel pressure regulator. a failed regulator can let extra gas into the engine through the vacuum line on it. Take off the vacuum line to the regulator, and watch the regulator for a minute with the engine running. If gas starts oozing out of the vacuum port at the pressure regulator, the regulator has failed and must be replaced.
If pressure is correct, at least you have eliminated that as a problem. Check the air filter, check spark plugs and plug gaps, more or less back to basic tune up.

1999 toyota tacoma has developed a nasty miss but only when excelerating

There are several problems regarding a misfiring engine. You can try checking all the spark plugs and seeing if they are good . Check the Spark Plug wires for any breaks or loose fit. If possible get a code at Autozone or other autoparts store. they do it for free. Because it could be a simple sensor problem Such as the Crankshaft position sensor, O2 sensor etc.
By eliminating the electrical ignition problems you can start to troubleshoot the fuel. Check all filters (ie: fuel filter, air filter, etc.)

I have 98,000 on my 2004 sable. It misses a little on exceleration. Should a replace plugs, what do I need to tune it up? Thanks

If you have never replaced the spark plugs I would do that first and also change the fuel filter. Try those first and go from there.

I have a 2000 chevy blazer 4.3l engine\is backfiring

Start by checking each cylinder for spark with a good spark tester. A misifre is either spark or fuel, so you can cut the problem in half. The engine light is probably on due to the misfire.
