Hi All - new member, first question!

I've had a 5 door MY99 for 3 months now. I'm very happy with only one (OK, two - see below!) niggle - on a trailing throttle at around 2500 to 3000rpm I get a sort of "on/off" hesitancy when accelerating "mildly" (under hard acceleration there's no problem).

This is not bad & I think I'd have a hard time getting a Subaru dealership here in Switzerland to recognise it. It's similar to a slightly rough idle in feel, but it seems to pulse. Once clear of 3000rpm pickup is smooth, regardless of accelerator load. It's worse from cold, but is never really intrusive - at first I assumed it's a poor ECU mapping.

However, I just read an excellent thread regarding the BOV (steep learning curve for me!) - in it someone mentioned that the BOV bleeds to atmosphere, messing up the input air sensor readings leading to a rich then lean mixture when it tries to recover.

Could this be related? Where is the BOV mounted & is it easy (& safe!) to "play" with the spring loads?

Niggle two is my reverse gear - very hard to select from cold, I normally have to release the clutch a little (to nearly grind point) before being able to get it in. Releasing clutch in neutral and blipping throttle does not work. Anyone had similar?

Many thanks, great forum!

MY99's do this as "standard".

Problem apparent if you hold revs in 2nd for a few secs then floor it.

blip the throttle before accelerating.

 

also - see thread below - 'hesitating engine'

 

I think its almost sure to be bov related, as garryc says, have a look at the other thread.

Dowser,

To help selecting reverse, depress the clutch, move the lever into fourth gear, and then quickly into reverse. It works for me.

Rgds,

My MY00 does has this 'hunting'
characteristic. Hardly noticeable but certainly more so when cold.
