Re: 89 Aerostar 3.0 Engine Codes

41 CM = Oxygen Sensor / Code 41 indicates system lean. Look for a vacuum leak or failing O2 sensor. I Replaced the Oxygen Sensor !!!

still getting Codes 89 KOEO & 86 KOEO..

and now getting Code 11 = System ok..

But now can't get Van Started !!!
Help Help Help !!!
