2001 Ford F-150 used to stall when I put it in any gear and gave it gas, so starting small I replaced the fuel filter, no biggie. Now truck stalls when I put it in reverse. Ive heard of the inertia switch but never dealt with it could this be causing my problem or do I just need to pour in some fuel additive and hope and pray? ---

Not the inertia switch, they have to be manually reset, like a circuit breaker in your house. Tell us more: Engine Mileage Transmission Drive System Last time plugs were changed Once rolling, how does it run. If you have not changed the plugs, have a compression check, both dry and wet, performed when you do. Is check engine light on? If so, what codes are you getting. Expensive way to repair: Throw parts at it and hope to get lucky. Cost effective way: Proper diagnosis. Sure you can through some fuel system cleaner in it, you **might** get lucky. ---

If no check engine light…I’d guess it is the idle air control valve…but that might change if I knew what engine you had.
