1992 Lexus 400 erratic at high temps. Anyone have an answer?
1992 Lexus 400 chugs or stops when the tank is about 1/4 full, or seemingly in higher
temps. Our local mechanic said it could be a float valve problem, and to keep the gas
above the "problem" level to avoid expensive repair. The chugging-stopping during
warmer days is a severe problem as we live in CA with HOT summers, and we have no
idea what is causing it. It was my daughter's car before, and she said it has been a
problem for her too. In cool weather, seems to be fine.
