Sc400 was running great. Then started missing lunging and dying, died after two or three starts, auto parts store recommended sea foam, due to us having a hard rain. I found clamps loose around air meter box, tightened them, and noticed a lot of 10 mm bolts missing which hold that box in place. Yesterday, it ran rough until I returned home, and the a/c only worked when the car ran great. Today, I found a broken vacuum hose fitting and attempted to fix it, but the car worked so bad, I towed it home with another car. The A.C had stopped, clutch was not engaging. However, after I backed it into it's parking place, and turned it off, I turned it back on, it ran perfectly, and the A.C was cooling again. I still need to permanently repair the broken vacuum hose, and replace the 10 mm bolts, and I suspect that the clamp near the throttle body was not tightened either. And it may need new plugs, possibly a new fuel filter, could be a fuel pump. I would say I have my work for me. What does all this sound like to you and why the A.C quitting as well? Do I need to undo the neg on the battery and reset the computer? I just bought it last month, and I think I have found a lot of the previous owners problems. I have a car fax, and there was two owners. Obviously, one or both of them did not care much for maintenance. Help me please
have the same problem?
