Hi,I need help. I have 91 G60. I bought a car which was not working so what I did:
I changed head gasket,set timing(I think),replaced distributor cap and cables,spark plugs,replaced ECU,Blue temp sensor,o2 sensor. Pistons and valves are OK.
However problem that I have is:
Car is running poor,smokes but it smells like gas at muffler (not dark black smoke or White smoke),no power.
any ideas what else I need to check.
