Need some help!!! LTRIM troubles!
I have a 98 A4 T/A with the following mods.
98 A4
Patriot 2.02 heads (1998 style)
Comp Cams 228/228 581/581 112
TCI SSF 3600 3.73's
MAC's/ORP
LS6 intake
Ported TB
stock MAF descreened
lid/KnN
all the free mods.
I need some help figuring out why one side is way off from the other side. At idle the ltrims are way off from each other. B2 is @ 10 and B1 is @ -4. The car had a LSX intake on it and I thought that might be the problem so I changed it and put the LS6 intake back on it but it is still off the same as before the swap.
So, I pulled the headers and checked for leaks and that was all good. So I put it back together with new gaskets and it's still the same! I have no idea what the problem is and I don't know where else to look. I do know that as soon as you give it some gas it evens out some. It doesn't get perfectly even but it does get close. Could it be a bad O2? How do you check to see if an O2 sensor is bad?
Also, when I pull up to a stop the car wants to stay idled up high for a few seconds. How do I go about fixing this problem?

Sounds like B2 is getting unmetered air from somewhere, look for exhast leaks near the collector and make sure your getting a tight seal on the 02. You can check your 02 with edit or HP tuners to see if there switching. If there not then you have a bad 02. Are you throwing any codes??

Ive got a very similar problem except at wot my 02's read 100 mv difference and it causes pinging. Ive swapped 02s and it stays the same. I think mine is injectors though.
If I were you I would swap 02's just to eliminate that. Are they reading the same at wot? Could also try running a can of top engine cleaner with a full tank of gas GM makes some stuff that is great costs about 10 bucks gets rid of carbon also.

Chris make sure both 02's banks are switching and not stagnent via LS1 edit or HP tuners. If there not start from there. I had the same problem in a 98 A4. It fixed itself when I changed out the 02 extentions (the switching part) Shoot me an IM on AIM when you get a chance.

I know this is an old thread but after trying everything, I swapped the cam (228/228/588/588/112) for a small cam(222/222/561/561/112)
The LTRMS are dead on now.
How could the cam cause this? Like I said, everything had been changed except the cam, so it had to be the cam, I guess
