Cold start/ full rich mixture problem
Hello,
serious 1981 help needed,
on the first start up the engine runs very rich for approximately 90 seconds and no M/C solenoid ticking, check engine light on, no sooner I feel the air switch solenoid click then it runs normal then check engine light turns off, I can restart car several times back to back with no issue but if I let car sit for 5 minutes or so and restart car will go full rich again until the 90 seconds or so and then clears up, replaced the o2 sensor m/c connector, anyone experience this with their cars, your help is greatly appreciated.
Thanks
