"Bogging" in first gear

MightyBobo · 07-03-2012, 12:09 PM

So interestingly enough, my car has had that "dead spot" in the lower RPM range lately, and I have an oil cooler. My temps weren't even past 200 I believe, at the time. I've also noticed that randomly while idling in neutral, the motor will suddenly drop RPM briefly as if it's about to die, and then catch back up again. It seems completely random when it happens - I'm tempted to pull my MAF's and clean them out a bit, or at least reset my ECU. Fairly convinced it's a tuning issue for me.

my car also seemed like it wanted to die at idle. this happened when the car was completely stock. I then added g3's, 19 row cooler, berk exhaust and tune and the car still bogged down at idle. I thought it might have been the fans kicking on and putting load on the electrical system but the two wound up being unrelated. I still don't know what it could be, I had the fan control tune from uprev and it did not help. whatever it is, it has never happened on my g37 sedan.

I'm hoping my 2012 is not gonna go down that path. I'm planning to do an oil cooler install after I get the springs, stabilizer bars and spacers done with.

if u haven't experienced it yet then your probably good. mine did it intermittently since new. I don't notice any loss in performance but it cant be normal or else everyone would have this annoyance.
