Maybe someone can direct me to thread. Im sure this must be explained somewhere I just cant find it.
cold start (40-50 degrees sitting in garage) the car always fires up immediately. then idle spikes up and down 500rpm rapidly every second ( this is a new problem) I can hold gas and keep it smooth. after 30 sec or so its stable but idles around 600 rpm until it warms up and then idle sits at 750. It never stalls..
its a newer dgo ism.. maybe a year old. Ive cleaned it out and oiled it..
today I started it up cold and it started doing same thing. I quickly pulled the plug on ism and the idle stabalized at 750 and it ran smooth no issues.. Im going to test this a couple more times.. I just want to understand this system better. Maybe its going bad already. My other question is do I even need it if the car idles smooth without? I was thinking of keeping it unplugged a few days and seeing how it goes..
any advice or re direction to another thread is appreciated..
Dave..
