I have a 2000 integra gsr w/ a blox type r manifold, type r throttle body, and i/h/e setup. My car was running fine until one day it started reving up and down from 1k to 3k repeatedly. At this point the CEL came on, but the car was runing ok. So i brought it home, tried to fix teh IVAC. the idle is ok now but the car cel read solid. So i bougth a new Erics tuning ecu, jumper harness and now am running on this new ecu. I know for a fact that this ecu works fine because it ran on another gsr perfectly fine. HOwever, the car runs fine now for like 10 minutes and then out of nowhere the CEL comes back on and it goes into limp mode. The weird thign is, the car doesn't even start w/ teh old obd 2 stock ecu. the fuel is shut off for some reason. we checked all the grounds, got a new battery, alternator, and distributer but no imrpvoement. the car starts fine and runs fine at first but then the CEL and limp mode. anybody have any idea?? please help!!!!
