Every once in a while when cruising at 47ish it feels like my converter is locking and unlocking back and forth then after a couple times it unlocks and stays unlocked.

What is this a problem with usually?

Tranny? Converter? Sensor? I have an SES light on, but I haven't checked it out fully. It's been on from a bad O2. So I don't know if it's thrown a code of it's own or not.

Thanks

 

Random engine missfire can cause that and this could be related to the O2 sensors or something else. Its not likely the converter or trans

 

thanks for the quick reply. I've also had random misfires once every few months since I've owned the car. I don't have the money for an o2 right now either.

I guess I'll double check the codes tomorrow and deal with it for now.

Thanks again, still loving the tranny/stall otherwise!

 

So I changed out my o2 finally and the cars runs really smooth.

BUT the problem is still there. Still getting a random misfire too.
