Has anyone replaced thier fuel filter because of sluggish, hesitation after startup? I'm thinking this could be the solution to my problem. I'm having issues after startup when pulling out IF i don't let the '06' 3.7 warm up and idle for at least 20 secs. It'll try to stall and will not go if I start and engage gear, as though it's not getting gas. This will go on for 5-7 secs. then it'll accellerate and resume normal drive. Never seems to happen when I let it warm up for a few. I don't think it's the pump, I hear it running and shut down when key is turned. any ideas?
