Not Done:
Clean flame arrestor (Recommended method?)
Check compression and leakdown (This one can wait, I think as engine runs fine)
Check resistances/ functions of the various senders for the ECM either manually or let a dealer tech use the Merc scan tool...especially the temp sender (Where can I buy my own)
Done:
Replace plugs, cap, rotor
Replace fuel filter
Clean pcv valve
Check ignition timing
Run a heavy dose of cleaner thru the fuel system/ ensure good injector pattern (Although it hasn't been run through the system yet)
Deep, I used brake cleaner on my factory arrestors...sprayed fronm the inside out.
On the scan tool, I'm not sure where you could pick one up...maybe a dealer??? My Seloc and Clymer manuals show how to check a few of the sensors with a VOM.
