We have a 1986 gas auto trans LeSharo that is having a problem.We can drive it for 15 miles and then it backfires and BOGGS down,then you can smell gas( like flooding out)it will cut of but start right back up with no problem.Have had plugs replaced( 2 times in one month),fuel injecters,fuel regulator,temp sensor and gas filter replaced but nothing is helping it,have even had new connectors replaced on the wires with the sensor.Can anyone help us?
Sounds like your fuel tank vents are clogged. Easy quick fix is to drill a small hole in your gas tank cap so vaccum doesnt build up in tank. To test run engine for awhile then open gas tank cap, if air rushes into tank your tank vent is clogged. Just like trying to suck the air out of a plastic bottle, eventually you cant suck anymore. Same thing with gas tank.
