Intermittent CEL?

First of all I'd like to say hello to the world of preludes. I've recently become an owner of a 93 Honda Prelude VTEC (original) H22A1 and i'm very much enjoying my new ride.

But now to a question i would really like to find an answer for...

After driving my new prelude for a few hundred miles (with no issues), suddenly my check engine light flashes on after driving for only a few minutes. I do not notice any loss of power or bizarre circumstances to make me believe it is a serious issue. however, being an OCD California Driver, i am seeking suggestions on what could cause this, so i may fix it ASAP. If i turn off the car, and re-start it, the CEL stays off... for a few minutes and then kicks on again. it stays on for the duration of my drive (again, no apparent driving issues).

I feel it could be a loose connection, or a bad vacuum hose, but i'm wondering if anyone else has run into this problem before?

In my old mazda, i know there was a way i could jump the diagnosis and have the CEL flash me messages, is there anyway i can do this with the prelude as well?

Re: Intermittent CEL?

even if its only throwing it intermittently, the ECU will store the CEL until it gets cleared, so you can still check it:
How To: Diagnosing Your Check Engine Light (OBD I)


and moved, since this isn't the right section.

Re: Intermittent CEL?

just a followup, I ran the test and got a number 12 code (EGR). took it off, and discovered it was quite gummed up. Cleaned it, and the problem seems to be fixed.

Thanks again!

I'm a newbie. I got a 93 non vtec. how do you check the CEL when the car is running? I did the paper thing under drive steering area and can not seem to get the CEL code?

Re: Intermittent CEL?

I really appreciate the quick reply. I issue I'm running to is when I turn off the engine, the CEL goes away and goes not stay lite with the key in the 'ON' position. Here is my issue:

1. start the engine and stay in idle (5speed) 10 minute or more and CEL does not come on.
2. then I drive to car around for 2 or 3 minutes and CEL comes on. I try to do CEL procedure mention above (while the car is running) and not getting any CEL to blink
3. I turn off the engine and turn on the ignition to 'ON' only and CEL does not come on.
4. What do I do?

Thus my delimia...

I really appreciated the help.
