Report "Usually starts & idles ok until it warms up then when you hit the gas it stalls.Then it's hard to start and you can't give it gas or it will never start but if you keep cranking it will eventually start & idle real rough and just start idling normally. When you start to go if you feather the gas and get it to rev up you can accellerate normally.I checked ecu and it put out a code 43 (my book says either o2 sensor or fuel problem for a 1993 honda del sol d16z6) I removed o2 sensor an got no voltage even after heating tip with propane torch. will a bad o2 sensor allow car to run ok one minute an then stall the next. or might I have two problems?"
