Reasons for power loss
Hey everyone,
To cut a long story short, my accord euro seems to have lost a noticable amount of power everywhere from 3k rpm up. Wondering what some possible reasons for this are?
my guesses:
faulty ecu
faulty master cylinder
a bit of background:
I've had my master cylinder replaced once already at 10k km and it is due to be replaced again this friday (approx 19k km). I'm hoping that this is somehow affecting the power? and then when its replaced it fixes the problem (it doenst feel as though the clutch is completely engaging/ disengaging)
i've also had the 20k km service so i know its not old/burnt oil or anything...
i've also had problems with ecu after i had a stereo installed (car would lock itself, and interior lgihts wouldnt turn off in auto mode)

nope, not that i've noticed...
i've been recomended to check the air filter and the grounding wire etc... hopefully it's a simple problem

How much power are we talking about and how long have you had the car? MY TSX is pretty sensitive to weather. If its really warm outside it gets sluggish.

fdl, i've had the car for close to a year (approx. 20,000 km).
It was winter here in australia when i first started noticing the problem (technically spring now).
Basically the acceleration felt at 5/6k rpm is hardly any different from 3/4k rpm.
I can still make it up hills etc (its not that severe) but it was noticeable enough for a friend to notice the difference in power... I was full throttle in 2nd gear at about 5krpm and he thought i was acclerating as per normal (say 3rd at 3k rpm).
basically it just feels sluggish - something is holding it back.

Well, i've got the car back after the 3rd master cylinder has been put in...
I still haven't taken it for a good drive yet, but it seems as though replacing the master cylinder has given me back some missing power.
I spoke to the service manager and he said they took it for a test drive before and after and that the mechanic noticed a similar sensation of power loss to what i did; the car fealt as though the clutch wasn't properly engaged when it was fully released and trying to accelerate.
The clutch feels noticeably weaker than when i first got the car now though and less bitey... probably because ive done 20,000km - the majority of which was on faulty MC's.
Hopefully the car is back to normal for a while now
