Lacking power
So only had this car for about 2 months now, picked it up with no problems, great history, has 80k miles got it for 14k (neighbor's dad moved away.)
but all the details aside he's not an aggressive driver and the car was in near perfect condition! I did notice though, when the car is cold or warming up the power on the throttle feels as it should, crisp! when the car warms up, (exhaust sounds a bit quieter too, I have aam short tails) oil temp is about 200 (normal I'm guessing) the car feels sluggish. throttle response is a bit slower and car revs slower as well Any idea what it could be? I don't think I'm in limp mode, I'm not limited to a set rpm 3.5k or 5k No codes, cel or anything |

I'd take a look at the Intake Air Temperature (IAT). The ECM starts limiting power at a fairly low temp. IAT is measured at the MAFs and can be looked at using an ODB/CAN scanner.

Yeah, unfortunately it's normal. Sprint booster or a tune are the only options to solve it, or keep the revs higher. It's something to do with warm engine and emissions that Nissan messed with it. Look up "the370 throttle response" in google and you'll see a lot of people with the same issue.

FWIW; My car oil temp sits at 180 in till i start getting on it then it will raise in the 200, 220 if i stay on it. i do not have an oil cooler |

But thanks everyone! It feels a bit better knowing it's a manufacturers problem, Definitely looking to get hfc, gen 3s And ecuteck! And a oil cooler ofc, Just wondering, are the camshaft or crankshaft sensors been a problem for this car? As it did with the 350z and g35? I've had both cars in the past and oil gunk would shut off the car or limit power at times |
The heat problems are from the cats being directly under the engine. I switched to ppe long tubes and my oil temps dropped to a consistent 200 when they were 225 prior. Added mishi oil cooler and its 180.

Had to look deeeeeep into the forums, but i found it!
I'm 70% sure I have the same symptoms that other people were having as well. http://www.the370z.com/engine-drivet...e-problem.html I'm not mechanic but I couldn't find a diy or anything, how could I fix my "brake switch"? |
Older VQ's have the oil galley issue.

Try this first, the user pushed the pins back into place to resolve |
If imjello's suggestion about the pins doesn't work, see the FSM for switch adjustment procedures.
