Idle Issues

[xj220]

Here's the problem I've been dealing with lately. When I start up my car for the first time (cold start) it immediately dies afterwards because the idle is too low but with a little playing it finally stays, but idles at about 600 rpm (as opposed to the 900 I'm used to). Once the car warms up it drives fine and idles a 900 rpm. I've never had this problem before. Usually when I start it up it idles at 1200 rpm until I tap the gas and then it goes down to 900 or so. Any ideas as to what is going on?

Do you have an electric choke? Maybe it is not functioning correctly? When you play with it do you mean you hold the gas a little until it warms up?

We do have an electric choke. Yeah, I give it some gas until it can hold itself. If the choke is bad, is it an easy fix and how serious is it? Thanks for the help.

Sounds like your fast idle cam is sticking and not dropping when you set the choke the first pump.
clean the choke linkage with carb cleaner and test it.

Alright, I'll give that a shot. Where on the carb is the choke linkage?
