A bit of a guess here.

I think you said there were no codes? Correct.

Check the coolant level....check the compression in each cyl....post the #'s.

 

There is an important ground attached to the thermostat housing. I would disconnect that ground, clean the eyelet and bolt with some sandpaper or a wire brush, then reattach.

You can try pulling the backup/radio 7.5 amp fuse in the engine bay fuse box for a minute to reset the ECU.

Remove the snorkel off the throttle body and spray starting fluid into the intake while an assistant tries to start the car. If the car will start up or run poorly for a bit, then you may have a fuel problem.

 

Thanks guys. It seems to run fine now...seemingly the problem was the cracked coil. It is just odd that it ran poorly for a while after getting the new coil. I will report back if it doesn't continue to roll along.

BTW, never any CEL.

 

Well good to hear it is back to normal....maybe the plugs needed to "be cleaned" off...meaning weak spark caused them to become fouled and it took a bit of the engine running to clean them off?

 

Thanks Poorman,

That is what I hope. It is still running fine.

Do you have any thoughts about the cracked coil? No signs of over-heat...just cracked. A Honda coil with only 10k on it.

 

OK,

I am back at my problem. On the way to work today, at 45 mph, the car just shut down. I rolled to a stop. It restarted. Five minutes later while parking it did the same thing.

Joy.

No unusual CEL.

Ok, is the coil fine?

 

Here is my Accord update.

Recent Sx: cranks and starts and idles for 30 seconds as it should. Then, stalls.

I messed around with the inside of the distributor cap, and it ran for two minutes before stalling. The cap is OEM an has 8k miles on it and looks fine. Except the rotor has worn slight grooves in the plastic at the base of each plug electrode.

I put in new after-market cap and rotor. Now, the motor starts and idles for at least 5 minutes. I will continue to try to get it to stall/test it. Recall after I changed the coil, the car ran and drove for two days before dying.

Thanks for thinking about this.
