Sweet Mother of the Blessed Acceleration, it's back!
That odd glitch I mentioned a while back where the CEL is on and it wants to run like a bat outta friggin' hell...totally uncharacteristic deep growl from the intake, and a nearly neck snapping rush (by comparison to normal) of acceleration from 3000-4500 rpm or so...it's hilarious...breathing through that punched out airbox it sounds like a Honda when the VTEC comes alive...
It feels more like how the 3.4 in my 2000 Impala would pull when you stood on it...there doesn't seem to be any change in WOT upshift points or anything, so that's not anything to do with it.
So this time I got the codes, since you all were curious (me too)..
It's storing PO125, Insufficent coolant temp for closed loop fuel trim, and PO116 Engine coolant temp circuit range/control problem.
It's not a problem for me! It's a welcome gremlin. Wish it would stay, or I could duplicate it. But typically it goes away in a day or two, we'll see. The difference is a lot like that with engines I've power chipped, only this I would say is even more noticeable. Like I said before, the idle stability is just a
bit off...most people would not notice the difference I'm sure...and it doesn't stick around long enough for me to accurately gauge the difference in fuel economy...
I suppose the other interesting thing would be to see what the emissions look like with this occurring...bet it's pretty dismal...I see no soot in the exhaust though, and the front plugs looked very clean....so it's not terribly overfueling, like to the point it can't use it all....
Keep you posted...wish I could quantify it and sell it as a performance mod...
