CEL & Limp Mode today???

Gran Coopay · 11-26-2007, 12:48 PM

Today heading to work like normal and an IS350 is tailgating me. I PROcede'd to toast him. In manual/step I drop from 6th to 4th and go from 80 - 105 or so, then limp mode and "service engine soon" lights come on. I have v1.47 and have had the boost target limp mode before, but this was different. I still had power, sort of, but when I accelerated a violent shutter began. I pulled off the freeway to restart, and as i'm slowing to pullover all the CEL's went off and it feels about only 85% as before. Has anyone else had this happen?

As you slowed the CEL's went away? Interesting. Sounds like misfires to me. If they went away thats good. Try unhooking your battery for about an hour to reset the ECU.
