Has it had a tune up lately? Check your plugs & wires. I fit is fuel starved it may could use a fuel filter. I would also check for vacuum leaks. The throttle body, IACV, MAF may need a cleaning. Only spray off MAF with CRC MAF cleaner & use CRC Throttle body cleaner to clean the IACV and throttle body, remove those two and replace gaskets.

Not sure where potato or tuna came from but yes it's at a recent tune-up and a new fuel filter and check it for vacuum leaks and check spark plug wires I'm going to check out the tbi today and the injectors and filters .thanks
