Klaus, I put a brand new MAF in and new plugs and removed the codes. Car did fine for 3 weeks but I am now getting the 2-3-2 code again and the exhaust smells rich again. The check engine light is off and on again like before. I am worried about things getting worse again and I get stalled. What is the culprit? I cleaned the MAF sensor plug. All the hoses seem good. The only thing I suspect has not been changed in a few years on this car is the 2 oxy sensors. Could they be the problem and if so, why? What do you suggest? ~ JG
