90 GT, 306, B303 cam, GTP heads, 97 Explorer intake, shorties, underdrive, cold air with 70 mm EGR, Throttle and MAF housing. Original MAF sensor. 24# injectors, stock ignition, 5 speed, 355 gears. Port work done on heads and lower intake. 185 T-stat. Electric fan.
The thing actually runs strong. Pulls easy to 6000 and feels like it would keep on pulling. Basically I built a high compression, ported 93 Cobra engine without the proper PCM and MAF. The MIL came on and spit out DTC's 34, 41 and 91. I dont have any fancy equipment to tell me what the AF is. So i pulled a couple spark plugs to get a look see. Obviously its running rich. I reinstalled the 19# injectors, changed the EGR and drove it home. The MIL came on again and gave me the same three codes. It idles and ran better with the 24#s in it. FP is at 39 psi vac disconnected 30 psi connected. Should I get a custom tune? I need to pass inspection. I installed the Smog system to pass the visual inspection, but with the GTP heads it is obviously inoperative. Can this set up be made to work well enough to pass the sniffer?
