Recently my car has developed a rich problem while cruising. It hits a 10:1 air fuel while cruising down interstate or in town. It's intermittent thus hard to diagnose, although it is doing it more often. I've tried 3 different maf s so far and my O2 sensors are new. This goes along with another problem I have on cold starts where it leans out to 18:1 and sometimes dies. Both problems are worse with the cold and the car doesn't have any codes. I've check multiple times for vacuum leaks also.I'm leaning towards the computer, but would like to hear any opinions on possible problems.
