Ruff starts for my 1997 cadillac eldorado?

My cadillac has been having ruff starts for a few weeks now. I took off the EGR valve and cleaned it up good, replaced the spark plugs and wires, changed the fuel filter and have been putting in fuel injector cleaners. What else can I check for? Other than the starting it has been running great.Ruff starts for my 1997 cadillac eldorado?It would be easy to hook up a vacuum gage, and as many vacuum lines as you have, and as old as they are, there could be a problem.



A poor vacuum could be giving you fuel injection system trouble with the mass air flow.
