When I dont drive my car for about 2-3 days it feels damn smooth and quick but when I drive it like everyday or for like over an hour or two I feel like the car is getting tired and i need to press the gas harder. Anyone having the same problems or got an idea with whats going on?? I want to fix the problem...thanks!

 

mine feels like it does the same thing....i thought it was all in my head

 

sounds like your flux capacitor is going bad to me.

 

Yeah its starting to annoy me now...cause I love how if feels when I havent been driving it in awhile. I want it to feel like that everytime i drive.

 

Might just be you get used to how it feels...? Mine doesn't feel as fast after a while and I end up dropping loads of cash for no reason to make it "faster".. All in my head.

 

I dont think its in my head cause i also had a friend drive it when i havent drove it for 2-3 days and he said the same thing too. Also I was merging yesturday and I wasnt even flooring it in 1st gear..took it to about 4500-5k rpms and shifted into 2nd real quick and the shit chirped...wasnt even in my powerband. I didnt even mean to do that but i bet u if i tried my hardest to do that when my car is "tired" I wouldnt be able to.

 

heatsoak in the motor might have a lot to do with it, carbon deposit buildup, who knows...

 

maybe the engine is just warming up. cold equals power. more dense the air more power you get so over time if the engine heats up then you lose some power in a way. and it could be from carbon build up and various other things. i didnt drive my eclipse for like 7 months and when i did drive it again. that fucker felt like she ran 10's tho when it came apart it was runnin very low 14's and when it went back together it was only runnin i'd say low 15's high 14's its all in your head i'd say. cause i knew mine was haha. just like in my head the integra is horribly slo. even tho i know it can run into the 15's stock. it feels so slow.

 

how would i get rid of carbon deposit build up???

 

stick a pressure washer in your exhaust pipe and turn it on.
