My 78 450 SL sometimes runs like it was new. sometimes it feels starved. I have NOT yet replaced plugs, wires, cap/rotor cap. fuel pump, fuel filter. I just got done doing that on my 75, and I am like here I go again. My 75 runs 100% better with all the new goodies, but I and others have noticed a real gas smell while the car is running from the exhaust...a friend followed me home the other day and commented on it. The 75 runs pretty badly, and I am ashamed. I also have a fuel waste that is almost un believeable in it. What could it be? It runs alittle funny cold then heats up and is like presentable to drive, but not what it should be. I know this was a 2 parter question but I am ready to commit suicide. Anyone know what to do or try? I know it needs to go to a specialist. But I am determnined to try to understand it and try to fix it myself. I know that is ego...but I have never had this with these 450's before. Usually it was a wire or plugs or fuel filter, etc. Thanks for the help! I mean it!
