I have changed my IFR and voltage table for injectors and still running lean at idle around AFR +17. I started redoing my v.e table and my number were a lot high than before. Please let me know what you guys think. Can log you pid in EFIlive to voltage at the injector?
Thanks guys

If it seems uncontrollable and random, plobly ripped a O ring putting them in. I did the same thing let me see if I can find my old thread.

FYI my oring looked fine but a new set fixed the problem...

I put some lube on them before putting them. The a/f stay same unless i get the vacuum close to 20 and a/f will drop close to the command a/f. So I'm leaking air around the injector?

Thats my guess, even if the IFR is close it shouldnt be that bad, especially after a little ve work.

Obviosly leaking on the botom of in injector, if it was the top you would have a gas leak.....

The only thing I had to change in my tune to run the 42 - 44 lbs injectors was the IFR table. I notice mine is lean as well at idle under COS3 but does it really matter?

I read your thread its simlar. with new injectord it's leam unless i put foot on the gas rev to about 1200 and let vaccum get close to 20 and a/f is great. So i'll stop by the dealer and get new injector o-rings and trt it again.

MIne lean at idle and driving truck around the block and yes that bad.

You don't need to monkey around with the voltage offset, I don't understand why people do this. I just changed the IFR table for mine and my AFR idle is perfect at 15.1:1 Who told you to change the voltage offset?

Only change it trying to get the a/f to get back in line. When left stock my a/f was in the 20s. Now that changed a/f is in the 17. I'm just trying to fix the problem. If have any ideas on this let me know.

I can't open .tun files with HPT but try this for your injector settings. I have 62PSI of fuel pressure at idle and this is what I used.
