Hi guys,im new here...i would like to ask u guys where should i go if i have problem with my S15..the problem is all my sensor light on dashboard not appear before starting engine(sometimes happen sometimes OK)..this problem start after i got problem with my ignition coil..after checked,one of my ignition coil detected not working...so i changed one of my ignition coil and the problem at engine side seems OK(no jirking anymore),but the censor problem still on and off+my car always "mati" when i step on gear 1 to move..usually when traffic jam or slow moving(air flow not consistent base on engine sounds)..i went to ae workshop and checked the computer condition there are two error code appeared: 1)mass air flow sensor 2)IGN signal primary..as u know ae most formerly known for its subaru specialist so here is there any recommended workshop around subang jaya or puchong for S15(reasonable labour rate)?...other than links dyno tune please....peace~~~
