Hmmm. I'm trying to think. What was the last thing that was done to the car before you had the issues. Things you believe that are minor are important in getting to the root of your issue. Even the most teeny, weeny, itsy, bitsy, cute, baby ones. ...and smaller than that too. New flash ROM's with different mods in the ROM where someone might not have loaded the XML correctly? Slice something inadvertently?

 

Hm, I don't think the XML would be the problem. I've only since added the 780cc injectors. I really doubt it was anything with the XML file that caused issues, because I had a tune done by a member and it was solid, it was after that I decided to add injectors and am now in the process of getting tuned by someone else.

I don't think I've added anything else since.

 

Any other suggestions? For my idling issues, I've noticed that once I come to a stop and put the car into neutral, the RPM's will dip to 500-600 and AFR gauge will read 10.0 and the car will nearly die, what could this be because of? IACV?

 

I say IACV if not an issue in the tune. Pretty much everything has been checked short of a leak down... and at this point, I think the car is solid anyway.

Fine someone to "borrow" and IACV from for a few and see if that does it... if it does, all is solved less the expensive part.

 

Part of the reason your car doesn't die is because it is rich at 10:1. ...be thankful of that. You could try to advance the timing in the idle load cells, to help, but if its not dieing then leave it.

 

I'm going to try 2 things, I will try and replace my intake and then the IACV.

Eventually will also do a leak down and send my oil off for an analysis as well.
