The car is a 91 VR4 Everything stock except for 550 rc injectors and a safc2,
The problem is that once it sees boost it boggs and if i let go of the throttle to were it doesnt see boost it will kick back up... Now there is an issue with the tps reading, sometimes it will work and sometimes it will not read anything... (looking at the afc sensor check and also verified reading with volt meter) I have tried cleaning the contacts betwen the tps and plug and also pushing the pins the plug harness to see if it will make better contact but with no luck, Also from searching here i have seen that peole will unplug there tps sensor when bad and things will clear up...(for trouble shooting purposes). So i'm wondering if the actual tps sensor is bad, because also my 02 sensor reading will work and then i will get no reading at all kind of like the tps but randomly, so sometimes tps works and 02 does not, and viseversa and sometimes they both work read... checked for codes but only get the tps and I noticed that when the tps reading is working No check engine ligth but when the reading is gone the check engine light will turn on, then reading again and light turns off...
So i'm stuck...
I have checked for boot leaks with a pressure test and will hold pressure so...
