Hi all. 86 22re with Saab t25, egr delete and intercooled. Hooked up a wideband and discovered my truck runs lean as rpms climb. Idles at 15afr. Unplugged the o2 sensor and it idles at 14.7. With the o2 unplugged with partial trotted it's at 12 and as I increase throttle it starts to lean out. It has new tps (these things are hard to adjust!) New fuel filter, ecm temp sensor, all new ignition parts. I opened up the afm to weaken the spring (give it more fuel) and it didn't really change much. I read somewhere that deleting the egr valve would cause it to run lean with rpm increase. Going to check fuel pressure tomorrow. Any help would be appreciated.  Thanks
