Hello guys:

Just recently i started to get a CEL#8 periodically. This would occur every once in a while. Last week, it got worse and would engage code #8 just about immediately upon the car leaving the garage. We also noticed that the car cranks longer to start up, unlike before when it would start immediately and it runs somewhat sluggish.

I took my helms manual and followed the indicated procedures as to measuring resistance and continuity to all the TDC, CKP and CYP sensors. Everything measured within specifications. I followed these procedures both from the 8 pin plug on the distributor and also on the ecu harness as well, just to be sure.

We took the distributor apart later that day and saw it had some brownish residue, which was likely the bearing that was going bad. So, i went ahead and picked up a nearly mint condition distributor and had it installed at home. I took the car for a short ride and it started up quickly as should do so and ran great. This was two days ago by the way. Tonight, i decided to start up the car and left it running for a while. I noticed that the check engine light was on and idle didn't feel or sound right. I started up hondalogger and to my disbelief, found to have code 8 once again!

I did all helms troubleshooting procedures again and it all turns out perfect. Has anyone encountered this situation before with such a strange outcome? The only thing left according to the helms manual is the ecu. Is there the possibility of a bad ecu? Maybe something heats up in the ecu and causes the CEL?

Is there a troubleshooting procedure i am missing or something i need to check but have not done so? I would appreciate any feedback into this matter as i am running out of options here.
