I have an 87 with a 305 TBI. It has dual tanks with the tank selector switch near the ashtray. On the toggle switch, up is the right tank and down is the left tank, and middle will kill the engine immediately. Just the other day after I filled the tanks, when I switch to the left tank the the engine still runs but with half the power and weak acceleration. When I switch to the right tank, it runs normal. Middle stills kills the engine. Any suggestions as where I should start to look for problems.
