ok so ive checked the error codes and i get a 1 and 3, and they are o2 sensor and mas sensor!!! the fuel pump is new, screen clean.. filter new.. the tps has been checked and checked and is within chilton specs. So ive got a bad mass air flow sensor. anyone know where i can get a working one or i may upgrade to 1gen eclipse t mas. Ive rebuilt this whole engine with +.020 hyper pistons, balance shaft removal, jet valve elimination, port mached polished head, stainless over valves..... so i think it qualifies for an upgraded mas, I just have to find one! Ive got the low oil pressure blues, its only at half and a little under at normal? New oil pump, new pressure sender.. slow original gauge? Any Ideas? Still trying to post some pics. also. it says there to large? I dont know how to reduce? Thank you everyone for the help.
