My 89 Pickup idled very, very fast. I've replaced the manifold gaskets, but engine still idles "fast", and it "seems" to take a long time to warm up.
I've written "fast" because I don't know how fast is fast. But I do have to apply the brake to stop the pick-up from accelerating. I've written "seems" because I'm not sure, but it does take longer than my old GM van used to take to reach normal temp.
Any clues
Thanks
John
