Ive got the TRD S/C, TRD CAI, DTLT's and the NST Pulley. These mods have been on the truck for 2-3 years. (Some longer than others) A few weeks ago when I was on the way home from work I noticed that when I put the truck in neutral (because I had a turn coming up) the RPM's went up to 2k then back down below 1k then back to 2k then back to below 1k etc. etc... I then got a engine light for P0451 EVAP Sensor voltage low. I cleared the code, truck runs fine except when in neutral it does the rev thing. About 2 weeks later I get P0171 and P0174 lean codes. I take it to the dealership and they spend a whole day looking at it and cant find anything as to whats causing this. They tell me to remove the URD O2 sim and bring it back to them. I take it to another mechanic and he spent a whole day on it and cant find any reason as to why its doing this, he thinks it could be a program error in the ECU. The second mechanic even tried it with the O2 sim on and removed. So he leaves the O2 sim out and I take it back to Toyota and asked them about reflashing the ECU. They say theyll look into it. They call me back and say they want me to remove everything thats not Toyota before theyll look at it because it could be one of those mods causing the problem. I dont see how as these mods have been there for quite some time now. The service manager calls me and said they would go ahead and look at it again for me. They had the truck for 2 days and couldnt find anything as to why its doing what its doing and when I asked them about reflashing the ECU they looked at me like I was retarded..... So today I put all the stock pulleys back on and removed my fog light mod as well. Any suggestions? Also need some help with the fog light mod removal because its been so long since I did it that I cant remember where this yellow wire goes. I did the FLM where I used the add-a-circuit thing. Wheres this yellow wire supposed to go? It comes off the relay and goes into the fuse box where its spliced to the blue wire after the connector. I dont even recall messing with this wire.....
