Oil filled in two of th front spark plug tubes and dont kno about th back ones yet need to take them to a mechanic to hard to get to, and is miss firing.
Car has had major issues with fuel economy, intermitent smoke, running rough for quite some time. I only use 93 gas as it no longer tolerates anything else. Car is in good shape so trying to keep it running. I came to this page because right now it is sitting in a parking space and wont start. Like it isnt getting fuel. We now think the gas gauge is broken and could be out of gas.
