The person I bought the E320 from has been using regular gas in it for 6 months. I put premium in it last week and now it makes a ticking sound after you go over 25 mph. at star up it sounds great, i think I need to reset the computer timing. can anyone help?

Welcome does your car have the electronic set up with coil packs or a distributor

A 95 will be fully electronic - no distributor.

timing not externally adjustable. hfm has knock sensors and maps to determine timing.
