I'm out of ideas. Help please!
Alright, 2005 VIII, I bought the car with a handful of bolt ons, kelford 64s, and a tune. Tuned to 25psi. I've been slowly uncovering that there may be bigger issues than what i had thought. When i first bought the car a few weeks ago I didn't notice the issues, but being my DD i am noticing it. If I drive the car and have to slowdown for stop lights, signs, or traffic I notice that the rpms drop way down. The oil light comes on, and the car then picks itself up and sits at about 1000 rpm. The other day, my brother wanted to hear me rev the engine up, so I bumped it to about 4000, not thinking this would be a bad idea. As soon as I let go of the gas the car shut off. I started it right back up, and just out of curiosity I did the same thing, right up to 4000 and it died again. So i figured, maybe fresh plugs and an oil change would help the car out a little. So i put in ngk br8es gapped to .025. And the oil was mobil 1 5w-40. (This is what the previous had records for being used.)
I then go for a little ride, and still the same problem exist. I am out of ideas..
HELP ME!
Thanks in advance,
Curtis

when you rev'd it up did it hit the 2step limiter? If the fuel for the 2step is wrong it will kill the car.
AKA. Get a tune from someone reliable AKA Chris @ Pure Drive Performance
BTW You should get BPR8ES or BPR7ES and gapped to .20-21 since your above 20 psi imo.
What Clutch/Flywheel combo does this car have?

I'm still learning a lot, what is the 2 step limiter?
And what difference does the protruding tip make compared to not?

Most likely a tune issue. Are you running the defrost at the time it dies? My defrost used to kill my VIII coming to a light in neutral. I had my tuner raise the rpm's and now it's fixed.
Also, run stock plugs for that amount of boost (heat range 7, gapped to .02). 8 is one step colder.

Thanks guys. I called the guy I'm gonna have tune it, went for a ride with him and he said it seems like whoever supposedly tuned it before did a terrible job.

could also be an issue with the IACV (idle air control valve). I've personally seen people have issues with this a handful of times. I am guessing that because of the time of year, you arent running the AC when this is happening? The reason M8NSTER was having issues with the defrost is because the AC compressor cycles when it is on, requiring an idle bump to compensate for the added load. A dirty idle air control can make it difficult to keep the car running at idle. You may also have a vacuum leak as well, have you checked all of the lines?
Seeing how you have the kelfords in there too, like others said, the tuning may be the culprit. hope this helps some, good luck!

Where is the IACV located?
