Ok Ive got a mk3 supra running a 1jzgte and r154. Basicaly when i first brought it it was smoking (blue) once it had being for a drive and didnt have much power once on boost, so i tigtened all the intercooler piping and it ran alot better but still has a misfire. So I pressure tested the intercooler and all the piping and it showed up pretty good. Checked the engine fault codes and it displayed 14 (Turbocharger Pressure) and 24 (Intake Air Temperature Sensor signal). When the engine is cold in runs really well has loads of power and dosent misfire but once it warms up it starts missing and runs not as good. I installed a boost guage and it runs 12 psi, im not sure what the stock boost is something like 10.5? might have dodgey vaccume hoses or it may have had wastgate mods, I will check it out once I get some time.
So I was wondering if anyone would have any idea what the intake air temp sensor is doing. Could it be beceause its running more boost and the standard intercooler cant cool the air. or is it not working at all and dosent detect the motor has warmed up and runs the motor richer. Any ideas on what I have to check and where? Thanks a lot
