seems like when it's hot performance sucks
so I've been having this lack of performance for a while. sometimes it works great awesome and sometimes it seems like it's restricted and it really pisses me off because I've had some close calls where i needed gas but it accelerated slowly.
I swapped my MAF already. I saw some improvement but still sucks (and my gas mileage decreased a little)
- Before swapping the MAF I was getting roughly 10.2L/100km but now it seems to be 11.3 ish. Perhaps because gas stations have changed their gas to summer? or perhaps my driving not sure. not too relevant I don't really care about this problem.
I've noticed that the longer I drive the vehicle (bring her to operating temp for a while) the performance starts to suck more. Where as when the vehicle has just been turned on to the point where it has just reached operating temp the car works great.
But as for the lack of performance, yes I do have the famous 3.5L rattle.
Should I replace the precats? if so, what should I tell my mechanic when I bring her in? and roughly how much would it cost?
could it be my precats that's been the problem all along?

Where do you notice the power loss? High RPM? Do you run premium?
If the car has more power initially and then losses it as you run it could well
be heat soak as others have mentioned. NWP ! ! !

^ listen to the above. Cooler temps mix better with fuel..... Giving better performance.. However don't expect ridiculous difference, it's 100+ here.. Heat will kill power on cars, Especially our vq's from what I hear.
