I have an '83 rx-7 I recently bought it's giving me trouble starting in the morning, or after it has sat for a while. It turns over fine,but takes a long time to fire, and even then it doesn't spring to life but gives a few false starts. Then I have to keep my foot into it because it dies if I'm not giving it gas (I've had it die a few times between 1st and second). It idles really low, like between 0 and 500 rpm if the tach is right, when cold too. Any thoughts would be helpful.
Thanks

 

mine has the same problem i tried replacing the o2 sensor but that didnt really help

 

As far as I've been told, my car in particular (87 FC) has issues starting in the cold. I know that I have to start the car in neutral and give it a couple of revs on a cold morning. I don't think that will solve your problem from your explanation but you can try that.

Aside from that, perhaps you have a bad throttle position sensor. I know that I have to replace mine.

 

I think for some reason the car just isn't getting enough fuel. That and I need to increase the idle. I'll be stopping at my Dad's shop this weekend so I'll have a look while I'm there.
