Help asap ( reduce engine power )
How's it going guys I have a 2001 c5 corvette 5.7 M6 bolt ons an cam (ms4) running 36#injectors so my question is why does my car go into reduce engine power in cold starts I checked my dtc an got p0106c an p1514hc an there's more codes but this were the only codes coming out when car was getting tune other codes were HC if I keep the RPMs up in cold star at idle it will not go into reduce engine power ....... So there's something going on wit the MAF or tps. But I dnt kno were to start I got a volt meter an had key on engine off an cheked the tps so ik is a 2 sensor in 1 so I cheked the 2 middle wires been the voltage reference an I was getting .3 on both wires don't I need to atleast get .5 .6volts idk if I'm doing it right can someone let me kno if I'm doing something wrong or have had this problem after tune thanks....
