See my post on top of 2nd page. Car usually sits for no longer than a week or so. Exception was over this past winter, it was down for 5 months. But I had pulled the injectors off the rails when I took the car apart so they say for 5 months with no fuel. They were fine when I took the car apart.
When Jon sends me the new set back I'm going to sell them on here. Since others have had good luck, it must be something unique to my setup. I assume its the extra heat mine sees vs someone who doesn't drive the car out of town for 4-6hrs in summer heat.

I forgot to add that this last time I noticed when driving it felt down on power. I stopped at the parts store for something and after starting it, it seemed fine. I ripped on it pretty good and hit the rev limiter. Immediately noticed a bad miss and it never went away even when cold starting. So whatever happens, happened that very moment of higher duty cycle (I only see 60% DC max).

Dang, making me think I need to pull my 160s as they are exhibiting very similar symptoms. Guess I will just be out the cash I spent on them. Maybe I will throw in some cheap 80s for now. What injectors are good in the 100 lb/hr range on e85 that are hi-z?

Got a feeling the same thing has happened with my FIC 72's. They are siemen dekas more than likely 60's opened up a little.
I called and asked if my 72's could be opened up to 80 and he says that's not a problem. I'm going to have them inspect them first to see if some were clogged.
I have been chasing issues with my tune....or so I thought.
I raised my base fp from 40 to 60 and was in the process of retuning it my self but couldn't get my VE right and my STFT's were all over the place always.
I noticed one bank would read +40 while the other would hover around +30.
I pulled the plugs and all 4 on the driver bank were light grey/tan color and weren't black or wet or anything out of the norm.
Pass. side had one black plug and two that were very very light tan color with no change over line at all on the strap. Which from what I've read the line where the color on the strap goes from grey to a tan color and where it changes at just dictates whether you have the right heat range or not. Either way it wasn't on three plugs out of 4 on that side so something isn't right.
For whatever reason while all this is going on the car won't idle or cruise at any AFR other than 13.80 or so. Stoich is setup for alcohol and is at 9.89 I do believe. Speed inc. tuned the car on e85 and 40psi base pressure and it would idle around 14.5-14.8 AFR when picked up. Now my fuel trims at idle will be +/- 5 and wideband was showing 13.80ish as always. Very strange to say the least.

From the first or second page, it was said the 160 and 200 (1600 and 2000) have the same core and are both CNG. This is what Jon@FIC told me as well, which is why I am ditching the CNG injectors all together and going with the Bosch 127s. Jon even recommended that.
