People, Need help urgently!!, what do you think?? Recently I switch from the TRD s/c setup to the naturally aspirated setup again. The thing is that after finish the swap and do the first run, it shows a crazy fail!!, doesnt respose!! Runs like a shiet!!, After a couple of minutes it shows the following codes : P0171 and P0174. I started the troubleshooting cleaning the MAP sensor with alcohol (it was really dirt), then after that i ensure all vacuum lines are properly routed and fixed. Everything looks fine!!. I had no choice then and I took the truck to a near toyota dealership. After 5 or 6 hours of troubleshootin of the technicians, they can't figure out which was the problem and finally deduced that the most probable root cause of the problem is that the ECM still with the TRD programing reflash for the SC, They told me that there is no way to get the computer back to the factory settings and I would need to purchase a new one!! Any recommendations?? Does any one have a stock ECM that can sell me or borrow me in order to confirm their theory?
