90 deville wont run right.
Okay im still trying to figure out why my 90 deville wont run. I ve done a total tune up on this car had tps tested, Rechecked all plugs and wires checked fuel pressure which is good. As i was taking out plugs on the backside of my engine i noticed that the o2 sensor between the motor and the cat was broken off and just hanging from the wires. I know this needs to be replaced but is this why my car doesnt want to run worth a ****? I was on my way home from kansas city, a 3 hour drive when i just suddenly lost power. My fuel economy went from 16 miles to the gallon on the highway to around 4, Yeah 4 and i could not get my car to go over about 40 mph no matter how far i pushed the accelerator. Only code i am getting is idle control motor which needs to be replaced also but that should only effect the car at idle right? Ive adjusted the plunger where it will keep the car at idle without having to hold my foot on the gas. I cant seem to figure out why i am not getting a code for the 02 sensor being broke in half, is my ecu going bad? I heard something about blowing ecu chip from driving without o2 sensor is this true?? Someone please give me a hand here I need my lac back!!!!!!!!! I just bought it and ive only been able to put about 600 miles on it! Plus in the mean time im stuck driving wifes 95 FORD pos taurus. Someone help please!!! Thanks
