I'm not really sure what's going on lately with my car, but I'll give you the basic rundown of my problems....

My setup: AEM, Stock fuel, T67, Meth, Built Auto w/3200 stall

First thing:
About a month and a half ago my mkiv started doing this thing where before the car warmed up, it would rev to like 4000 rpm before it shifts into 2nd gear. After the car comes up to temp, everything works fine. The transmission seems like it stays firm with the shifting and everything is fine. I don't know if this is related to the EMS...

2nd thing:
Shortly after this problem came about, something else happened. When i start driving my car, if I give it moderate partial throttle the AFR's drop to the 10's and it starts acting like its going to die, or it does die, then the problem goes away. Could this be a wideband problem?

I checked the transmission fluid, its full, but smells burnt and needs to get changed
I had a boost leak where some vacuum caps came off, and replaced them, but i'm pretty sure this is unrelated

I would do a datalog for you guys, but my laptop is down at the moment

Any ideas?

perform AEM's wideband test procedure.. It's on youtube....

That will tell you if the wideband is spent.

Are you sure you don't have an issue with the transmission itself?
