Ok so about 2 months into owning my 97 gst and the car was amazing the first 4 weeks of owning it and the previous owner had done some mods to it you can see them on my profile long story short I wanted to get a new radiator fan from mishimoto got the plug n play and it blew tons of fuses a30,a40 and a50 because the connection is wrong anyway and then the cold weather came around and the car started to idle mind you I unplugged the hose to the radiator to put the new fan on and now I have replaced iac valve cleaned egr valve since I can’t find one tried to adjust tps sensor and adjusted biss screw nothing seems to work it’ll rise in rpm when idle and it will stay at high rpm while driving once I let foot off of the gas pedal like it’s stuck and so I took it to two o Riley’s and one advanced auto parts scanner said it was a o2 sensor b1 sensor 2 I also knew because my car has been running super rich I can smell gas and everything and air fuel ratio gauge can’t seem to find a balance always bouncing between 16 to 28 and just yesterday while car was at idle I disconnected the tps sensor and the rpms slowly were dropping slowly but once I plugged it back it started to rise and my apexi gauge said I was on throttle about 8-2% when my foot wasn’t even on the pedal does this sound right tps and o2 sensor is what is causing my issue? Also checked for leaks nothing boost leak tested 3-4 times nothing and yeah water pump is getting replaced right now so I need help any help hopefully those two sensors once replaced and re adjusted will solve it
