Car is acting funny...need imput

Ok i'll just say that i've not gotten a tune yet to get rid of the check engine light for running an o/r H pipe

1st gear was acting very sluggish, it felt like i was starting out in 2nd everytime, and than 2nd gear was being sluggish to at times. It was worse on an incline.
I unno but i think it has something to do with my AC being on cause i turned it off for like 2 miles and it was just fine
but even so my AC shouldnt had that much of an effect right?

it was just weird.

Your AC shouldn't affect your performance that much like you mentioned.

Bad batch of gas maybe?

As Chris said...the effect on performance when the AC is on...should be minimal.

If the car was acting fine before without the tune...I would rule the tune out. It has to be something else. Pop the hood with the car running...turn the AC on...and listen for anything that doesnt sound "Normal"

mine has been idling super low lately like 500rpms...idk what it its its even stalled a couple times

Check the connection to your mass air...I would also pull it and clean it with MAF cleaner. Screw it back down and make sure it seals.

k ill do that tomm... ive done it before so it should be easy cheesy

my buddy was having the same problems. just had his THROTTLE CONTROL SENSOR replaced. car runs fine now. youre welcome...

Let us know what you find out.. Im curious

I think Deez had to replace his TPS as well as David C. Could be the same symptoms. I will say however that you need to get that tune to turn off the rear O2 sensors. These new systems are pretty sensitive. Prolonged use and throwing codes could cause the car to remit to fail safe mode?
