94 Jetta GL 2.L
just bought. Gave tune up. Runs GREAT!! However, very, very hard to start cold. Can push start easily. Cold start sensor may be issue from my research. Where is sensor? and do you concur?
That's a possibility. Also a dirty Mass Air Flow sensor, or bad IAT (Intake Air Temp) sensor, dirty Idle Air Control valve, or bad engine coolant temp sensor. Anyone of these will give you a hard start.
