HELP! Severe acceleration lag

Ren425 · 10-29-2016, 02:46 PM

Thanks guys. Getting more insight. To break it down a bit further, the car feels as if it slips/hesitates between 0.8-3.2K RPM. I suppose an analogy is like your dog is on a leash and the you've got a grasp of your dog who wants to run free.

The catch is, I've already installed a oil cooler from 2 years back. Usually keeps my temps between 180-220 depending on how hot it is outside and how lead-footed I am. LA traffic definitely contributes to higher oil temps.

Do you guys still think it could be related to IAT, oil cooler or oil temp related? Heat soak is definitely a factor, but the problem only comes around when the Z reaches the 220-230F mark.

If it were the brake switch would it occur at any oil temp?
Could also be throttle response at that specific oil temp?

I'll have to see if the problem returns after like a quick stop on the side of the road or re-cranking. Further comments are appreciated, cheers guys.
