I got a code 10, and recently a code 1. I have since replaced the o2 sensor, and now it looks like i have to change out the TA sensor as well. The air temp sensor went just last night, but i have been getting bad gas mileage aka running rich all week. my 88 mpfi dx 5spd got atleast 300 or more to a tank b4 i bought it, and now i got 160-170 to a tank. Does anyone know if this sensor takes a while bfore it sets off a code? or is it a sudden thing? I cant afford gas right now, and i need to know if replacing that sensor will restore my gas mileage or not.
thanks, dave
