So i was racing this integra gsr (winning at that) mis shifted and went from the 3rd to 2nd. When it went into second it kicked it out of gear and my check engine light went on immediatley after. It also is really boggy until i get above 3k then it seems to run ok. I checked the code on the ecu (pr3) and it gave a code 1 or single flash. I put another pr3 ecu in the car and the check engine light came on before the car was even running so its not the ecu. I check the distributor out, it looks ok. Then the next day I took my fuel rail, intake manifold, o2's and shit out and checked them out and put them back in. I also had a spoon vtec controller that I took out to see if it was the problem too. I started the car and let it idle and the check light went away and it seemed fine. Then I left my shop and about 1 mile later the check light turned back on. it also started the boggy before 3k crap as well. Im lost here guys. I took it to my local speedshop and they dont know whats up either. Anyone had a similar experience or know anything I should check? Current set up. 1991 civic hb dx standar. B16a engine. Skunk2 manifold. STR 70mm TB. Obx header custom made with 2 bungs for the dual o2's. aem coi. greddy exhaust.
