Im a rookie at this so bear with me. Also, if theres already an answer to this Im sorry for making a new thread, but I couldnt find anything describing my situation.
91 z32 n/a mostly bone stock. No intake mods or anything. All new vacuum hose. AIV deleted. Straight pipe and egr deleted. Also, i removed the coolant lines under the upper plenum.
ANYWAYS, when its all warmed up it idles around 1000 consistently. When i turn my defrost or heat on it shoots to like 1500 and stays steady. Then of course it comes back down when i turn heat off.
Another thing I noticed is when i go into neutral she hovers around 1500 for a moment then will settle down to idle at 1000 (unless of course the heat is on)
Am I missing something obvious?
Thanks in advance for any knowledge.
