Default HELP: Vsc, Trac cont., Engine check----

ok lights came on and the car started backfiring or sputtering at around 3500 rpm's

i hit the gas hard and since it was raining the wheels spun and traction control went on and then right after everything lit up car drives fine under 3500 rpm's

i just had headers installed and i need a new exhaust manifold gasket because they are leaking a little bit.


please help

i reset the ecu by taking out the EF fuse i believe, didnt work, havent had a chance to disconnect the batt. ill try it in the morning

the last thing i will do is go back to the dealer, they knw what they are doing but cost me a fortune. i just got my ecu, MAF sensor and neutral safety switch replaced. the math on that adds up to lots of $$$$

im thinking its the o2 sensors. the sound the car is making reminds me of a WOT box on a car, revs up and hits 3500 RPM's and starts going bah BAH BAH BAH BAH . and the idle is rough

colin, chances are you have a bad MAF sensor. Clean out that MAF sensor and see if that helps. If not, get them codes. When I cleaned my MAF, it didnt work so I had to buy a new one. That solved the problem for me when it happened.

Yeah, probably a bad MAF. They are super stubborn and dont clean easily. Sucks that you have replaced it within the year. Let us know what happens.

turns out it was the o2 sensors they replaced back in march 2009?

they told me MAF, but anyway my MAF sensor was bad. it was reading about 158 grams per second....when my car was OFF, 70-80 at idle

normal is like 7.5 at idle, like 1 when the car is off.

but its fixed and i am DONE with performance crap on this car, exterior and interior here i come

I'm so glad that such a small percentage of xB owners have problems, and if they do, someone is always there to help.

My ABS/TCS/VSC come on often but it doesn't affect performance at all.
