January 13, 201412 yr Author It similar like this http://m.ebay.com/itm/150863250998?nav=SEARCH&sbk=1 thanks for link to manual i will try to check it
January 13, 201412 yr Your MAF is not in that manual. Probably not the problem. Check it w/an ohmmeter or voltmeter while moving the flap, Sounds more like a large leak in the rubber intake pipe/associated plumbing or PCV hoses. Check fuel pressure too.
January 13, 201412 yr ...1986 1.8 MPFI ... The MPFi EA82 engine is Rare in the USDM (united States Domestic Market), but very common in the AUDM (Australian Domestic Market), and LADM (Latin American Domestic Market) so, your subie's engine bay looks similar to this one, isn't it?
January 13, 201412 yr Author Yes it is , but it came to belarus from germany and the wheel is on the left side
January 29, 201412 yr Check the PCV breather hose on the intake boot, they like to fall off when you open the filter box.
