Hey guys another little problem im having is when i first start the car up in the mornings it seems to have a very lumpy idle.. up down up down.. if i leave it for a few minutes go outside and give it a little rev it drops and sits nicely at .8....im thinking maybe boost selenoid needs cleaning?

also when revving sometimes it seems very stick, it revs holds then drops.. any ideas? sticky throttle cable maybe.

cheers
Dan

 

bttt?

 

MAF perhaps?

 

possibly, only seems on idle tho

 

Other potential culprits:
old plugs, dead or dying coil-pack(s), clogged air-filter, sticking IACV
