Its running lean. So far, I've eliminated the ecu, distributor and rotor, plugs, cat. Thought I had it solved, but it cut out on me on the freeway tonight, then kicked back in after a couple of seconds. The dash lights work, so its not like I'm losing all electrical power, it acts like the motor loses spark. It doesn't buck like when a car runs out of gas, it simply cuts out and has virtually no power (pull). Its driving me crazy, so please help! I'm starting to think I've got a bad wire or connector to somewhere, perhaps between the ecu or distributor?
