Unhook the plug wires and turn it over, should get gas on 2 pistons (remove plug and see if they are wet) if one is bad. Best route IMO, buy a mpfi intake and swap it.

You may also want to check your main fuel relay. That could also be the cause as well.

When I had a code 16 it turned out to be my main relay. Easy fix, and honestly a must for these cars.

Re: 1989 Dual point fuel injection (DPFI) fault

the car starts and runs good. I get a light miss when idling. I checked the CPU out of curiosity and saw the 16 flashes . should I be concerned? how do I reset the CPU? thx.
