temp sensor is alright. tests good and is brand new. When i take the oil cap it bogs down, so I don't think its a vac leak. have also checked with carb cleaner all over. No signs of a vac leak.

Thanks for the quick reply. I have cleaned all the carbon deposits out of the AAR, it seems to work fine. When i pulled it out of the car to clean it the flap was just a sliver open. Ill put it in some hot water to make sure it closes. Could the corrosion on the thermotime switch possibly be the cause? I thought it turned off when it was done cranking so it shouldn’t affect anything past when it is started. Everything is leading to the AAR but it seems to be working on first inspection. Ill take a look deeper into it.

Hi guys, I have a 1978 280z that i recently picked up. It runs great and i’ve been enjoying it tons. Im glad to be a part of the community. When I start it up when cold the idle sits around 500, misses and lopes a bit. It doesnt smell rich at idle but as soon as I start driving it gets pretty rich smelling. So I dont think it is the cold start valve? Once it is warmed up the idle sits around 1100. It is set like this to keep out from dying when cold. It has no problem starting at all, just running after it is started. I know for a fact that the AFM and water temp sensor are good. I have cleaned out the air regulator and throttle body. That seemed to help a little bit. The thermotime switch looks to be a bit corroded but it is only used at start right? So as far as I can tell eveything in the cold start system is working. Ideas on where to go from here?
