Picture of supra for the soul

I have a 87 targa now I drove the car for about a month an everything ran great all of a sudden one day I got home just to leave and right back out and feels like it lost 1/2 the power. 14 21 31 32 42 43 52 is what I got when I ran the codes and I checked everything from coil packs AMF IC hose, and all is good now the ECU just flashes stating that there are no codes but it boost just fine it feels like a blown HG the car has power one sec and then next but there is no over heating or cream under the oil cap. could this be a bad turbo

Welcome back, glad you're ok. Smile

Pull the EFI fuse for one minute, stick it back in, then drive the car around. Then, pull the codes again.

This will tell us what codes you really have. (codes are stored, so some of them could be old)

Code 52 is for the knock sensor circuit. You should try the SOGI rewire:

Pull the 15A EFI fuse in the engine bay fuse box for one minute. Drive the car, and then pull the codes again after a bit of driving around. Let me know what you get this time.

ok I pulled of the IC and found some oil in there and in the piping, cleaned them out with some 93 oct and cleared the codes now I can boost the car over 0 vac to 10 psi, where I want to be anyway. And I have no codes now but which seal on the turbo is it that will cause the oil to leak into the IC and pipes, The Big one or the little one. this is a JDM Motor and no telling how long it sat up B4 I got it.

It would be the front seal if anything, it likely needs to be rebuilt.
