1995 Chevy Impala mileage: 64,000. Help! My impala is sick, I have just had the timing chain, distributor, replaced, also a second set of plugs and wires. My husband the back yard mechanic also added gas cleaner, thinking that I had gotten some bad gas. The car was running better, the main problem had been the distributor, but now it sounds like it is missing when its idling, and it is making this loud noise like it has an exhaust leak. Could all that stuff he added to clean the gas caused damage to sensors, or the catalytic converter. What do I do?

The wrong gas additive can cause damage to the oxygen sensor and/or catalytic converter. Check the catalytic converter to make sure it is not “plugged” or restricted. Your car is equipped with a computer controlled engine management system. An independent auto service center can scan your computer for fault or error codes. The information should pinpoint the malfunctioning components.
