Diegog sorry to hear bout that, Hopefully its nothing serious. Add another to the list. I too received the p0700 code this morning driving to work. Hit some ice as I was giving it gas and Bam code appears. I also have Diablo Predator 91oct canned tune. I Pulled over, put in park & turn engine off. I started engine back up & car drove (thank god). The car drove okay but wouldnt shift higher than 4k rpm. I stopped at gas station to return orignal stock back up & Check engine light went off. Car drove better, was a lil scared to give it gas for the fear the dang light would come on again. Will check lunch break & get back to you guys. Hopefully nothing too serious. Is this common for our cars???
