Hi Scotty. My apartment manager has a 1995 Buick Park Avenue with 173,000 miles. Has a code for random misfire in all cylinders. Doesn't do it that much unless he driving a little hard, usually goes 30 in 45 zones. He's 71, and I wanted to know what could cause this aside from spark plugs and wires. Changed air filter as it was black from something sticky. Thanks!

So many things can do that from a blowing head gasket to a weak fuel pump the failure and the ignition system electronics. Have a mechanic at least analyze to see what he says of course the problem is it's so old it's a 95 so it's only OBD1 and a scanner isn't going to give that much data
