2001 Toyota Camry engine hiccup problem: Need help please
 

My 2001 Toyota Camry (85000 miles) has started having engine hiccups. While driving, I sense a hiccup, transmission downshifts and if I try to accelerate, it hiccups again before picking up. One time at a stoplight, the dashboard lights came on almost as if the engine was not running. When I restarted the lights went off and it started. What could be causing the hiccups? Any help would be appreciated so that I know what to look for and how much it would cost.

Thank you.

When was the last tune up done on this car? Like plugs, filters, etc. Any check engine light?

The dash indicator lights came on but the engine was still running?
