Car goes lean suddently

[JoeJoe1]

I have the updated version of Rom Editor and ran my car for about 3 months with no problems with the S200, today while driving the car would suddently lean out and bog, two times it turned off on me one at about 60mph and another at idle. I thought maybe the Rom chip went bad so I changed it and it does the same thing. Any ideas???

Doesn't sound like a problem with the Hondata, but could be a wiring problem, bad injector/s, bad fuel pump, or clogged fuel filter. You need to look at the long and short term fuel trim in the datalog and look at other sensors to see what mihgt be happening.

You are right I fond out what it was, my kill switch hooked up to the fuel pump went bad but it got stuck on the on position, so it worked but somehow was causing the sporadic lean mixtures. Replaced the switch and works fine, Thanks.
