2001 Eclipse GS Spyder P0170 code
My car has 150,256 miles. I need diagnostic help to find out why vehicle is idling rough, I am receiving code P0170. It stalls at start. After starting and idle at 2000 rpms, short term fuel trim is at 24 while long term fuel trim is at 6, according to scan tool. When I step on accelerator it feels like it should be running great but as soon as I let go accelerator go, idle goes back to around 678rpm and STFT/LTFT remain the same. I have replaced EGR valve, IAT valve, MAF sensor, O2 sensor, coolant temp sensor, and TPS. Nothing seems to help.
