Good day, now for a long time i have problem with power loss, some of You may even be pis :tsktsk: d because my questions. But still, i hope there will be some advices. Some people said that i may have problem with pre-cat, because car is slow. There are no lights on the dash blinking, diagnosis shows nothing bad. But the power loss is huge after some driving, and even more after hard driving, trashing. First of all i changed the whole back of exhaust from the main cat to the exhaust tip(i don't know how it is in english), because it was choked. It feels a little better when shifting, the lag is smaller, but still... And now I even not always can feel the VVT'i kick effect, more and more often. So is it something wrong with valve? Or it may be the pre-cat problem for sure?
Sorry for a long storry, but i am letting down my hands and am thinking of selling it, but i don't want to do that !
Thanks ir advance
