New Car For Me:

So, I have driven the car a total of about 100 miles since I got it. Runs great no problems. Today on my way to work, I notice the Service Engine Soon light comes on. The car is still driving fine with nothing changing. When I get into the parking lot at work driving about 5mph and turning, the car stalls. Car starts right back up and idles fine. Put it in gear and start to pull into a spot the car stalls. It starts and idles fine and only seems these issues come up at very low speed.

Any thoughts on what could be the problem? I am going to get the car scanned at Auto Zone ASAP. Just wondering if this is something anyone has heard of or experienced?

Is the car an A4 or M6? Does it still have the stock cam? What year is it? What gas did you use, if you have filled it up yet? Check plugs and wires. Get it scanned ASAP.

 

Sorry, see above.

 

Lol, that came quick

Before the tune, mine had trouble at low RPMs.

 

Car was tuned using LS1 Edit. It has run fine up until this morning.

Would a bad Cat cause this?

Thanks,

Bill

 

Hehe, I noticed that it was tuned after looking over that huge list again

I am not 100% sure if it could cause it, but anything is possible I guess.

It might be hard to determine what the problem is at this point. Make sure you drive straight to Autozone after work

 

I'll go at Lunch and post what they find on the scan.

Thanks,

Bill
