My 96' Ranger has been throwing the P0171 code for a while, and the engine idles at about 1k - 1,500 RPM; if I don't keep my foot on the accelerator, the engine dies, even if I've been driving around for a good half hour or so (the engine is easily warm by then). It starts back up fine, and that whole thing will repeat if I don't keep my foot on the accelerator. It also seems to "chug" a bit when I'm going about 30 MPH or lower (for example, if I pull up to a stop light, the engine will "chug" a bit, and keeps doing it until I start accelerating, and am going a decent speed again. I've checked for an intake leak, but I can't find one. The O2 sensors all have correct voltage coming from them. Any ideas to get me started with more troubleshooting? Thanks!
