A few weeks back my truck started to stall when I'd hit the gas, usually it would just lurch and then fire up again, then it would drive fine. Lately it's gotten worse and has begun stalling as soon as I put it in drive. Idles fine, just stalls in gear. I switched out the fuel filter but no luck.

Any advice would be appreciated. Thanks.
