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.
Start with replacing the fuel filter.
there is a good chance your timing is out or your fuel filter needs replacing
Start with replacing the fuel filter, it may be plugged up. If the stalling persists, have the fuel pump psi tested.
After replacing minor components that would cause the vehicle to stall such as the fuel filter. Advance the ignition timing a few degrees and the engine will run better and there will be no more stall.
Hard starting and stalling. When in doubt, replace the filter.
change your fuel filter
Check the fuel filter and/or fuel pump.
Possibly bad fuel filter
Check all vacuum hoses first. If they are all attached & in good condition: Check that the air filter is not severely clogged/ dirty. Replacing the gas filter (s) may also stop this from happening. My bet is on the gas filter (s) or the vacuum hoses.
If it's hesitant/stalling on acceleration and stalling on slow down or stops, then could possibly be the fuel filter.
Yes, if it's clogged up.
It could be a clogged fuel filter.
