Alright guys I just got a 98 s70 T5m from Tom. Car is great but has a few issues. First off it idles around 1100 rpm also when i shift when accelerating the idle goes up about 300 rpms when i let off the gas. throws a p0505 code. Idle control system malfunction. Checked the Iac and it was fine and the noticed a hose on the left side of the intake manifold was off. Put this hose on but problem did not go away. When I first started the car after replacing the hose it stalled immediately after starting. It starts fine since then but still has those issues as I said. Any ideas?
