Sluggish

When i accelerate it feels like there is no torque it pretty much is running like garbage in all gears and i seem to get passed by mini vans while im shifting into 5th gear my codes say I'm running lean in bank 1 and 2 ,I've been bouncing around shops left and right and no one can seem to tell me what the problem is I've gotten 3 new o2 sensors changed my plugs changed my fuel filter I was told it could be my throttle body but I'm leaning towards a bad vacuum hose I'm wondering what's wrong and wear all my horses went

Try cleaning your MAF sensor with proper cleaner

And make sure your air filter is clean

Also check the fuel pressure under load

When i have a cold air inatke i had a check engine light turn on turns out that i tightened it on to tight and cracked the intake so i had a vacuum leak....( It was carbon fiber) It took me forever to find it.... It was really small but same symptoms car was sluggish and had a weird idle... I would clean the MAF with some cleaner from auto zone or whatever.... Then look for any obvious vacuum leaks... But you said your running lean so basically to much air and not enough fuel... Clogged fuel injectors maybe??? Do you have any misfire codes? Use sea foam that stuff works wonders!!!

No misfire codes I'm takin it back to the shop today cause we noticed they didn't put the o2 sensor on the driver side in all the way and it's lose and some wires were cut from it and I'm hopeing that's the problem

One thing everyone will always say is that usually when its a 02 sensor code its not the 02 sensor something caused the 02 sensor to trow off a crazy reading... So its something b4 the o2 sensor

galindojr24,

I think you're on to something as far as vacuum leaks go. With everything you replaced, there's not much else it could be. One of my favorite diagnosing tools is a smoke machine. You can get auto service shops to hook one up to your intake and find an air leak that way. It will cost you some to have the shop perform the test, but it's a quick way to find any air leaks!
