Could use any advice I had bought a really good well taken care of 1998 owned by a mechanic. Well the drive home was a nice smooth ride witch was 5/10 minutes from my house. Anyways the next day when I take it out and when I would stop it would vibrate and I suppose it would stall and has died once as I was turning on another road. So I took it to Autozone and they ran a test on it and it came back as something like bank (1) and bank (2) with fule lean well I replaced my (MASS AIR FLOW SENSOR) kinda felt better as if I maybe gained some power and stalls less but still not keeping idal. Now when I take off or in put in neutral or park it Idols like a brand new truck off the lot. Could this be oxygen sensors or O2 sensors? Or what is this any kind of advice will work. Do I need to kick the tire honk the horn slam my hood 20 times or what please please help. Thanks and head gaskets and all has been checked as they said oil and all is well and good updated. Heat a/c works great as well.

Bud, you've just got a vacuum leak. Check your pcv & vacuum hoses. The connector on the back of the throttle body is prone to leak. With a little investigating you'll have her running fine.

You know I'm gonna have to check it that's what I've herd many times today maybe it got pulled while checking air filter and tampering with houses thank you so vary much I'll check it out in the morning.....advance auto was talking as if it was oxygen sensor from the upstream before the cat. But I don't understand why that would relate in to I guess you could say miss firing. People that work around where I live are just in it to make money not help the community.

You might have an expert (?) see if your cats are getting plug. They have a finite life and can cause problems that no one seems to be able to answer.
I've been there and it took some big bucks to replace them but it solved the idle problem. It was a new truck. They failed at 216,000 miles.
Good luck.
