Idle Air control valve
A 1994 Cadillac Deville that has an engine surging problem and is stalling out can indicate it is not getting enough fuel. The fuel filter may be clogged.
A car engine stalling is not only related to air filter problems. If you air filter was plugged enough to make the car stall then changing the filter would have cured the stalling problem. It sounds like you have a fuel delivery problem seeing as the car will not go over 10mph. Could be a simple as changing the fuel filter. If that doesn't help, your fuel pump could be failing. This is for a non fuel injected vehicle. If your vehicle is fuel injected then the car needs to be taken to a mechanic who can properly diagnose the problem. Hope this helps.
I don't know about the Explorer but I had an experience with a Ford Mustang. I changed about everything I could think of related to the non-starting problem. Then I discovered there was a filter in the gas tank. Changed it and the problem disappeared!
i'll give you several answers . you could have water in your gas, you may need to replace your air filter, fuel filter, you may have a bad spark plug or spark plug wires, your timing could be off. i I have a 1998 Taurus and I had a stalling problem - took to shop and for about $27 he changed my hoses that was my problem, hole in hose and cracks from age of hoses.
Hard starting and stalling. When in doubt, replace the filter.
I would say if you have a sohc v6 4l engine than the iac - idle air control value is the problem. i fixed mine by cleaning it with cab / electric cleaner. that was for stalling when starting in the morning or cooler temp. I still have lumpy idle but i hear that the upper intake and lower intake gaskets are prone to leaking - i replaced them but did not fix my lumpy idle. Other people suggest fuel filter. I fixed my stalling problem but still have a lumpy ldle.
check to see how dirty your air filter is. if is too dirty it could cause the problem it was the cause of mine.
Could be the fuel pump or the filter. I had a similar problem for my 1995 explorer xlt.
change your fuel filter
Check the fuel filter and/or fuel pump.
Possibly bad fuel filter
If it's hesitant/stalling on acceleration and stalling on slow down or stops, then could possibly be the fuel filter.
