Hi there, for the past couple weeks me check engine light has been coming on and then my car will lose power while I am sitting at a light or stop sign. It takes a few seconds to start going then will ride fine until I slow down again. I have taken it into Autozone several times and the error codes I got said it was an Oxygen sensor or the MAP. I replaced the oxygen sensor, air filter and cleaned the MAP. The car rode fine for a day or two then started acting up again. This time I checked the battery and it said it was bad, bought a new one and it rode fine for two days. When it started messing up again I noticed on the new battery positive connector it had already built up a bunch of corrosion and a little bit on the negative connector. So as of right now I am completely lost as to why the car keeps dying on me while driving some days and others it will ride okay.

 

V6 or 4-cylinder engine?

 

It's a 4-cylinder engine

 

Have the regulator and alternator checked

 

You may want to checked any carbon build up on throttle body.
