Started up my new 6 bolt motor and noticed right away the idle was just as bad as when i took out the 7 bolt. The motor is running rich and missing alot. No CEL's. Well i hooked up my datalogger and saw my o2 voltage was .020 and that i was in 'Open Loop' (meaning the ECU is looking at the MAF and not o2 sensor -like if you were at WOT- for fuel control)
Well i replaced the 02 sensor and still not better! o2 voltage is still .02 and the car is still in Open Loop!
I hooked up my multimeter to the o2 signal wire at the o2 and got .0-.1 volts. i'm going to get another o2 but don't think this is the problem
Why is my car stuck in open loop at idle ?
