I just acquired a 94 945 turbo auto car that sat for 3 years. Replaced the vacuum lines, plugs, cap, rotor and fuel injectors with some known good for brown tops as 2 of the original injectors were bad. car starts and is somewhat driveable but as you slow down to come to a stop. It will also not idle very well or at all unless I keep my foot on the gas and in neutral. Once above 2k rpm it seem to run ok and have some power but doesn't seem much better the my 90 745 5 spd non turbo car. Any ideas of what I should be looking for?
