Re: on and off power problem


1) put a space after each comma

2) use full-stops occasionally

3) proof-read your posts so they are easy to understand

sorry mate but it was bloody hard to read that.

do you notice that there is any difference in the 'feel' of the brake pedal when you drive it, while its got issues and then when it is going nicely?

if the pedal feels different im going to place bets on your VCT solenoid being stuffed, and the cam timing being a bit out of wack, causing the flat note of the exhaust etc.
