Re: Did tune-up, car still runs like crap

["David Teitelbaum" <jtrealty@xxxx>]

How did you clean the injectors? To do it properly they must be done
in an injector cleaner to test them and clean them. Is the Lambda
working? The frequency valve should be buzzing loud on the right valve
cover. Are you sure you got ALL the vacuum leaks. Check that the hole
over the mixture screw has a plug in it. The ignition coil might be
bad, try a new one. Is the engine starving for gas? Check the pick-up
hose in the fuel tank, many of the old ones are soft and kink and
collapse especially when the fuel level is low. Maybe the O2 sensor is
dead. Check it as per the Workshop Manual. Is the timing correct? Is
the advance working? All of these things must work properly for a good
running engine.
