Hi I have a 1999 SAAB 93 with 95k km on its.

there is 2 problems that I can't figure out what, hopefully someone can help me.

1. The car engine knocks at idle, the characteristic of the knock seems like all cylinder reignited. No check engine light present.

possible causes (from me) vacuum tube or intake tube is leaking. I cut turbo to turbo solinoe hose short due to a repair.

2. The car shakes at 110. The rage goes from 90 to 140, 110 is the initiate point. I did wheel balance and still shake. Shake started after a wheel rotation.

possible causes (From me) I dont' know.

please help me.
