For some reason my 1987 Cabriolet won't directly start on a hill?
When it's parked on a hill or even a small tilt, you have to hit the gas in order for it not
to turn off after turning on the key in the ignition. It seems to start okay otherwise,
though. Is this something I should worry about, or is it just a normal thing? If serious,
will problems severely increase if untreated? How much will repairs cost? Thanks for
any help!!
