Hi all new here and new to Hondas, lots of great ino on this site yet I cant find anything specific to my problem. I have a 92 Integra LS Auto. It was a winter project, so I did all the mods at once without driving it. I put on a DC Sports 4-2-1 One piece header, JDM 60mm SS Exhaust with highflow cat. B&M Fuel prssure regulator set at 45# (this isnt the problem tho, as I tested without it and got the same results) New cap, rotor, plugs and wires. Dropped it with some Maxspeed coilovers too but thats irelivant to the situation.

OK heres the problem, Starts up just fine revs nice and smooth and has good power and economy. "Il leave for work and come to a stoplight and the idle will keep pushing the car if I leave it in drive, if I pop it in neutral the RPM's will rev upto about 3k then drop back down to normal, I put it back into drive and all is kosher untill the next stop light where the same scenerio happens. All this with no check engine light.

Once the temp gets upto normal operating temperature the Check Engine light pops on with a code 12 and the car purrs like a kitten the, no over revs at all, runs and drives fine. I'v checked th EGR lines and the unit itself with no luck. Can anyone here shed some light on my situation?

Thanks a bunch
