85 Fuel/air mixture problem
hey guys i have a 85 2wd 2.3 and i am getting horrible gas mileage, as low as 8mpg but usually around 15 and hardly any power it lunges while driving and rocks the the truck like a built up HEMI when i start it in the morning. My engine is running rich as hell, flakes and particles of unused gas come out of the exhaust, which is just a little ol grandpa fart with no compression hardly. It runs great and everyone else says so too, but theres 30% that truck is missing out on i just know it.
It idles about 300rpm's higher than the 7-9 im used to. (least thats what my ears and feet tell me. no tachometer) I took it to be smogged and it wont pass. he told me to buy an o2 sensor so i did and it didnt help a bit.
This one doesnt have a Mass Airflow Sensor. and i just recently unplugged my IACV and the engine didnt fluctuate at all. im thinking and hoping that might be the problem. or at least one of them. ive already cleaned it out a little bit, but i didnt take the IACV apart into two pieces, just off the vehicle.
i also heard that the coolant temperature sensor could affect the air/fuel mixture? i eagerly await your replies.
