Sounds like a vacuum leak. Vacuum leaks can cause backfires. Check all your vacuum hoses, some of these can appear to be connected, but can have a crack in the top. If you see this, replace the hose-most do not have a hose clamp to secure them.

There is a pcv hose at the backside of the engine that hooks into intake manifold. They will fall apart at the 90 degree bend and will need to be replaced. You will have to get this from a dealer. It may make the check engine light come on also. This happened to my car. You can reset engine light by removing battery cable for about thirty minutes.

Check your PCV valve and the hose that attaches to it. This PCV valvle is usually located on top of your valve cover and usually have a 90 bend in it. I would replace the valve and check the hose for any cracks. The PCV valve should look like thisbrickdog2000_0.jpg.

1998 ford expedition won't stay running, i can start it and as long as i keep my foot on the gas it will run, but when i move my foot it dies quickly


Start with the vacuum hoses on the motor, this will do this. the vacuum hoses are rubber hoses three quarter inch in diameter on down to real small hoses and can be located anywhere on the motor or under the hood. Look for a hose off, cracked, broken, or loose at a connector.

Intermittent flashing of all dashboard lights


Weird,sounds like your battery connections are possibly loose, but
the car wouldn't start properly, or at all, if this was the case. You might just have a loose connection to the dashboard controls?
If you are up to the task, I'd remove the guage console,if you can,and make sure all the connections are tight. Good luck.

Car shakes when it starts and trouble shifting gears


I HAD A FORD FOCUS AND THE PROBLEM WAS A MANIFOLD VACCUM LEAK AT THE HOSE THAT CONNECTS PCV VALVE TO INTAKE MANIFOLD. THIS HOSE CAN GET SATURATED WITH OIL AND COLLAPSE AND TEAR CAUSING A NO IDLE AND SHAKING CONDITION. IF THE CAR IS AN AUTOMATIC IT WILL HAVE TROUBLE SHIFTING BECAUSE OF INCORRECT RPM SIGNAL TO TRANS. CONTROL. ALL IS DUE TO VACCUM LEAK. ONE WAY TO FIND LEAK IS TO USE A SOLUTION OF DISH DETERGENT AND WATER IN A SPRAY BOTTLE AND SPRAY AREA AROUND AND BELOW THROTTLE BODY BELOW AIR CLEANER ASSY. ALSO LOOK FOR HOSE THAT ATTACHES AT MANIFOLD BELOW THROTTLE BODY AND BRANCHES OFF TO PCV VALVE SHOULD BE A "T" GOOD LUCK!!!!!!!!!

Check the O2 sensor that is attached just after the air filter. It may be dirty and could use a good cleaning or replace it.

I got this problem when I was messing with the throttle, I removed the hose that goes from the filter box to the throttle not knowing there was a sensor on that hose that tells the computer how much air is coming through the filter. So when I started the car without that hose attached, the sensor was not getting any air causing the engine to raise the RPMs until enough air was going through the sensor. Since it was not attached, the car redlined before I quickly shut it off.

If its dirty it will cause it to not read the airflow properly.
