I've got a pretty old car (Nissan Pulsar J1J 1991 auto, 203K kms on the odometer) and it drives pretty well - I'm using it on a roadtrip across New Zealand and have taken it on pretty mountainous terrain without much issue.
The one issue I'm having with the car though is that when I try to start it in the morning (or after 5+ hours after the car was last driven), I'll need to step on the gas to get it to start. I've gotten the battery replaced very recently (about 2 weeks ago) and that didn't help any. In the mornings, the temperature is close to freezing but the problem has happened in the middle of the day too if the car hasn't been started in a while. It seems to be getting gradually worse, as the past couple of times I've had to try 2-3 times with stepping on the gas before I can get the car to start properly. Often, I'll also have to gently press on the gas periodically while the car is idling and warming up or the engine dies.
The last time this happened I had a half tank of gas. I haven't been paying much attention to the gas level though, but I will in the future.
I'm selling the car in about 4 weeks so am taking it in to get a full servicing. In the meantime though, any ideas what the issue could be? I'd like to be able to tell the mechanic what to look out for, as I'm sure they'll be rushing through everything on the service checklist.
