cooler temps causing funny engine idle
Noticed the other morning for the first time (temps in mid 40's) when I first started my truck, the engine seemed to have a small surge as it idled.
It was not a surge of increased power, but more a fraction of a second of decreased power. (Similar to an airconditioner compressor kicking in and drawing the engine down momentarily)
Compressor was not on, but it had a rythem to it, every 10 seconds or so, for a split second, the decreased power surge could be felt and heard.
Any ideas if this is normal or not? After it warmed up, it ran like it always did.
Thanks,
Rick
