I`ve been struggling for awhile now to keep my car alive after letting the throttle go after a high rev. At times only up to 3k. I`ve checked and tested the TPS and ISC and they all seem to be in good working order. I`ve adjusted the throttle cable so that it`s not tight and have a little slack. I`m venting to the atmosphere with a Turbo XS bov and never had problems before with it. I haven't done a boost leak test but my idle is around 850rpm and vacuum is at 20. No surging up and down that's associated with the ISC going out. Flywheel is not lightened. The ECU is not leaking(but has been chipped for 880 from po). At this point I have no clue what is going on with the car. My future plan is to get a chip from Keydiver to update the one I currently have, but for now I need to know what is going on with the car.
Here`s my mods:
T3 turbo w/ tubular mani and HKS gate
stock throttle body and intake mani
motor is semi built by Class1 and head freshened up by FRH
Here's my log...The problem is see is the my injector seems to be turning off when I let off the throttle. The blue is the rpm and red is the injp.
