I read a similar post but no resolution. My '05 Equinox starts fine most of the time, but when I make a quick stop before its fully warmed up I have to slightly depress the accelerator to get it to start. Now I know with fuel injection this should’t be happening but its been the case almost since the day I bought it. GM changed out the software in the computer and that seemed to work for a while, at least long enough for the warranty to end. It doesn’t bother me but my wife wants the car now. What’s up?
A defective temperature sensor could be the cause of this problem.
