Why does my car die when I put it in drive?

does/is CEl on? any codes in computer? try cleaning MAF sensor.

Not sure what CEI is. Only shows service engine soon but can not get it to autozone to have them do a scan on it. where and what is MAF sensor?

cel is check engine light. was it doing this before you changed pump and stuff?

Had someone check the sensor and that did not solve anything either. I was able to get it to autozone and have it scanned and again it only shows 02 sensor bad even though it has been changed. I had someone tell me it could be the coil pack or crank sensor does that sound possible? I have not been able to have it checked out yet as I am a single ****** of 4 money is tight and its hard to continue paying someone to do one thing after another.

when you say check sensor did that mean see if it was dirty? they all get dirty. another thing about ox is it can mean a vacuum leak somewhere. hoses crack/split/fall off and intake gaskets can leak. you need a vacuum leak test if no obvious problems are visible.

To be honest I do not know what they mean by "checking it". I do want to thank you for all your help so far I know it has to be aggravating for you because it sure has me stressed out.
