the 0210 code is saying the system is too lean. what could be the possible causes for this? For right now, there are only the two outer bolts holding the VI onto the the lower IM. We used RTV sealant on the gaskets, but could there still be an air leak somewhere? If so, how did did other VI users get bolts into the lower IM? I want to dyno on Friday, but im not sure if this is holding back some performance or not. My car seemed slower about a week after we put the VI on, leading me to think my KS died, but i just checked the codes again, and I only get the 0210 code. Could the KS be dead without getting the code?

 

I'd say that's your problem.

 

I forgot what I did to throw that code, but i think i was moving my air hoses around and messing with my air intake when that code came up. I honestly can't think of which hoses I was playing with.

 

Hafta agree. Using only two bolts you run the risk of an intake leak, and now you're getting a lean code? Looks like cause and effect to me.

 

alright, figured that could be it, just making sure it couldnt be anything else. Did you guys use the bolts in the rear to bolt down the manifold? how many bolts did you use up front? Do i have to drill into the lower IM to get to more bolts in there?

and is this robbing some of my performance? I work from 12-9 today, and I'll try to get it resolved tomorrow morning, but if its robbing some power, maybe ill wait to dyno.

 

If you're too lean, yes it could rob power... but more importantly, depending on how far lean you are you could be running into detonation territory under heat soak/load/wot conditions...

 

yikes. not good stuff. well, im off to work. if anyone could answer my question about the bolts from the VI to the lower IM, id greatly appreciate it. Thanks for the help. I love the ORG

 

Besides the two bolt holes at the ends of the IM, there are four in the middle - two on one side of the LIM and two on the other side. You should use all six bolt holes. Unfortunately, two of the holes already in the LIM won't match up with the holes in the upper, so you will have to do some drilling and tapping.

I also installed Keenserts to convert two of the existing 8 mm bolt holes to 6 mm in order to use the oem bolts.

Here's what I'm talking about:

 

If there is a vacuum leak wouldnt the idle be crappy? I would hook up a vacuum gauge and check for any funny readings.

Also when Krismax and myself installed the first 2K VI on his Max he got rich/lean codes randomly. We never could figure it out and he just kept reseting it whenever it came up. When I installed his setup on my car I saw that the vacuum line to the FPR was being crushed by the TB/IACV adaptor block. I just re-routed the vacuum line with a 3 way fitting and some spare hoses, so no lines were being pinched. I haven't gotten any codes from the swap and the car runs fine.

 

check your vacuum, it should be close to 20 in-Hg at idle. if you have a haynes manual check out page 2C-8.

 

ill buy a haynes manual and look into checking the vacuum. i know there is a vacuum hose that is kinda kinked right now, but i forgot what its too and im too tired to go look right now. even if there isnt a leak, im going to go about putting at least two more bolts into the lower IM. where do you buy keenserts from?

 

Some auto parts stores carry them. Having used both Keenserts and Helicoils, I have to recommend Keenserts. They are much easier to install.

By the way, I take it you are using a 4th gen lower IM, hence the problems with the center bolts?

 

I just remembered what made that code pop up on me...I replace my MAF sensor with a different one, but soon as I changed it back my car was fine.

 

i am using my same MAF. and yes, im using the 4th gen lower IM. Once done here at work, ill be taking the VI off and will be looking into installing the keenserts. Im trying to get it fixed because i still want to dyno today.

 

I had this problem but it was FPR-related. My FPR vaccum source was T-ed from another so it was inadequate. I have the upper IM bolted to the lower using four bolts; the two outer and two long bolts toward the middle of the IM.

 

did you use keenserts? what size bolts did you use? 6 or 8mm? How long do they have to be?

 

I ran this same setup, with no probs.

What I did with the 2 front middle bolts, I enlarged the holes on the 00VI, and then used bolts that would thread into the matching holes on 4th gen lower.
