I've had this car for several years. I moved out of the area and could not take the car with me. Once I came back, the had some issues but I was able to fire her up. For two years the car was not started, no maintenance, and some wiring and several parts were modified. Long story short, her last smog test failed.
1989 Taurus 3.0L about 136,000 miles. New oil, plugs, distributor cap, rotor, and wires. Here are the numbers:
IDLE: 980 RPM, CO2% 14.0 Meas, O2% 0.10 Meas, HC-PPM Max: 120, Meas: 201, CO% Max: 1.00 Meas: 1.88 ---FAIL
2500 RMP: 2581 RPM, CO2% 13.7 Meas, O2% 2.5 Meas, HC-PPM Max: 140, Meas: 19, CO% Max: 1.00 Meas: 0.00 ----PASS
So smog check failed due to idle high HC and CO.
She runs fine. When she start, no check engine ligth, then I drive from city to highway and shortly after 20-30 minutes, check engine light lights up. Diagnostics code pulled are I believe 14. but I am not 100% sure, can it be a 41? From the manual and some research code 14 is a PIP fault and/or TFI module malfunction. But a 41 is mixture too lean. Im not 100% becuase I am using the jumper method were I locate the Signal Return port and short it to the Self Test Input, then watch my "CHECK ENGINE LIGHT". So what I been able to collect is the following:
Key On, Engine Off:
1-1 pause 1-1 long pause 1 -4-1-4-1
I dont proceed with the engine on test.
Any suggestion would be great, also please, I am reaching out for help becuase I am trying to save some money by doing some work my self, I am not gifted but I can handle some work under the hood. thanks.
