It makes all manner of odd noises!
Going forwards, I go in to first and put my foot down, and it makes a really loud whirring noise like I'm in reverse... then all the other gears make that noise too when I floor it, but it's gutless as hell, and makes bad clonking noises if the revs get up too far. Could this be air starvation??
In reverse, it's very reluctant to go anywhere. Have to give it some revs, then it sounds like the alt belt is slipping or something... I actually thought it was going to go bang reversing back into my parking space the noise was so bad.
I'm thinking,
1) Gear box is on it's way out.... something is wrong with reverse gear which means it's making the stupid whirring all the time going forward, and reversing it's seizing up and making a belt slip? Fear is its the gear box?
2) It's just the air intake, would explain the noise if air is escaping somewhere, and the sluggishness when I accelerate.
At 5pm I've got to drive it the 1 mile home, and the way it is at the moment, I don't trust it not to just give up totally.
