Default another flashing sports light

1990 Honda Accord automatic

If I drive enough that the car warms up, then shut it off and try
to restart within a few minutes:

usually sports light flashes, but car starts. Have to shift manually

sometimes engine light stays on and car wont start. Wait 5-30
minutes and engine light goes off, car starts. Sometimes
sports light still flashes and have to shift manually

If car sits more than a couple hours never have a problem.

Worse in warm weather.

Problem started a few years ago when engine was steam cleaned.

Mechanic replaced a relay under the dash with no effect.

I removed the backup fuse for 30 sec to reset codes. When problem
happened I used paper clip on passenger side connector. I get the
following codes:
1 2 7 8 14

Code list I got online:

1. Lock-up solenoid 'A' circuit open or shorted.
2. Lock-up solenoid 'B' circuit open or shorted.
3. Throttle Position Sensor circuit open or shorted.
4. Vehicle Speed Sensor open or shorted - No signal from speedometer.
5. Shift Lever Position Switch circuit shorted.
6. Shift Lever Position Switch circuit open.
7. Shift Solenoid 'A' circuit open or shorted.
8. Shift Solenoid 'B' circuit open or shorted.
9. Counter shaft or transmission speed pulse generator open or shorted.
10. Coolant Temperature Sensor open or shorted.
11. Engine RPM (Ignition coil signal) open or shorted.
12. (No code 12 used)
13. Main shaft speed pulse generator open or shorted.
14. Linear (line pressure control) solenoid open or shorted.
15. Kick down switch circuit shorted.

Other than this problem car drives fine.

Diagnosis, suggestions, comments ?

Thanks

Gene

It's interesting that all the solenoids are signaling problems but it is highly
unlikely that all of them are bad. Perhaps there's a loose ground in common.
That steam cleaning might have breached some insulation at the solenoid
connectors near the transmission too. I had a similar problem recently on my
Prelude. I had to *completely* disassemble one of the solenoid connectors and
clean it thoroughly.

If you or your mechanic get to inspect those connectors, measure the resistance
of each solenoid while there. They're usually just a few dozen ohms maximum.
If any reading is several hundred ohms that solenoid should be replaced.
