Thanks guys for your help. Guess what, this morning it started fine, on all four. I had been thinking that I may have gassed before starting the other two times. Today i made a concious effort to keep my foot away from the gas pedal. I drive several cars, all the others need gassing to start, I could have subconciously had my foot on the gas, would this cause the symptons described, like flooding?

 

Very possible. It would take about 30 seconds to clear up but I'm still baffled that it would throw a CEL.
Are your other cars fuel injected? Generally speaking, fuel injected cars should be started WITHOUT your foot on the throttle.

 

Of the other cars, one is fuel injected anf the other not. I just tried my S2k again, both feet out the door, stone cold, started on four okay, no check light, I let warm up to 3 bars but I still think it is not as smooth as it was a week ago, at idle it seems to miss a beat avery 5 or 10 seconds or so, still no check light. I am puzzled. Over the weekend I will check out the plugs and see if there is anything amiss there. I'll report what I find.

wouldn't a missfire for a few seconds throw a cell then? Thats how long it took for the check light to come on

 

I believe it would, however, this car is well known for its erratic cold idle and not throw a CEL.
You might consider resetting the ECU so it can go back to its default settings and learn all over again. Having the throttle pushed may have caused it some confusion and it may still be trying to learn "your" way of starting the car.
To reset the ECU, pull the "BACK UP" fuse under the dash. It should be in the 3 slot on the right column of fuses (7.5 amps). Do it with the car OFF and put the fuse back in after 30 seconds.

 

xviper, if he resets the ECU, wouldn't that clear any problem codes set off by the problem? Wouldn't it be better if he took it to the dealer first and had the dealer check out the code, provided he doesn't damage the car during the drive? Or, does the ECU record every CEL code ever triggered in a log file permanently?

 

Yes, it would clear the codes but he didn't seem inclined to go to the dealer as the story progressed. I would have recommended not driving the car after the first time the CEL came on and had the car flat-bedded to the dealer but he has since driven it anyway, so. He should still have that code pulled before clearing the ECU but it's his decision.

 

My thoughts exactly

Well, I have not had to do anything. The car is starting normally and running fine. Whatever was wrong seems to have sorted itself out, even the at idle it runs without missing. The whole thing is a bit of a mystery, possibly by having my foot on the gas peddle while starting. I didn't clear the codes. I have not checked the plugs yet as my torque wrench has gone walkabouts!!! and I had better not under or over torque, I will trace it and hopefully have a look this weekend.

I have to say that this site is a great tool and thanks to you guys for your imput. Living in Portugal where there are not many Sk2s arround and not speaking the lingo well is not easy, the security offered by this site is great.

I'm going to keep a close watch on things. I get the feeling though that the cars brain is way out in front of mine!

Thanks

 

I am having a similar problem....car starts up rough, then idles rough and CEL flashes while in idle. Once i start moving(revs above 2krpms), the CEL goes solid and stops the flashing. Once i stop again the car idles really rough and sounds like its about to stall out.

I changed the plugs thinking they fouled, but it still did it. I removed my V-AFC and it still did it. Ive reset my computer after each thing, and im still stuck with the problem. I dont think its #4 failure as once im moving my car is just as fast and runs good, but idle it sounds really messed up.

Could it be a fuel injector? Or possibly the MAP Sensor? Im gonna see if i can take it in to service this weekend. If its something serious will Honda give me a rental?

 

There is a current thread about the MAP sensor and how you need to "whack" it to get it to function properly again. Ultimate Lurker is the author of that thread.
Also, what "supwithyou" describe is very much like as if you pulled the BACK UP ECU fuse and left it out. Should check to see that it's not blown.
