Here's the issue I started having after over 2 years with my S200b.

All of a sudden. The check engine light came on a month ago. I turned the car off. and started it up again, and all was well untill today.

I started the car. drove it for 1 min and bam! the check engine light came on, and it went into limp mode. I turned it off, started it again. it was fine for another ~1 min. this happened 5-6 times in a row untill I got home. I'm assuming it's a connection? but where??? what causes limp mode to come on?

oh - I have an 01 lude with a JRSC.

The ECU came from hondata ready to accept the lude harness
(No OBD1 -> II adapter)

The light came on when I was crussin on the freeway, and taking off from a light, off boost.

Are you sure it was limp mode, or was it just revlimiting at 4000 rpm?

Have you tried reading the codes by jumping the service check connector?

The car is throwing a code 14. The car runs fine when I'm giving it gas (greater than about 6% duty cycle). I'm also taken it to redline. It's just an idle thing... So, I don't think it's limp mode.

Last night I changed to Entire Throttle body. IAV valve, TPS sensor... everything to see if it was just the IAC. I started it, and same problem... Terable idle, almost stalls, code 14. I Re-set the ECU, the code went away for 10 sec or so, and back on, just like before.

The wierd thing is, if I turn off the car, the code gets erased... (Shows on the dataloger), then shortly after it pops back on.

I'm guessing it's a problem with the Hondata or ECU making something throw this code? Any idea's?

This sounds like a wiring problem. Try following the Helms manual steps for troubleshooting this error code.

That could be a problem... I don't have a helms...

Can someone pull the troubleshooting steps for me if they arn't excessive.

Problem solved!

It turned out to be the IAC two pin connector wire that was rubbing against the PCV line. It wore threw since the IAC was moved for the JR instalation.

Everything is back to normal.
