Yesterday we took a trip out to Yuma to visit my wife’s grandmother. Coming back through the desert, we enountered a thick, humid haze, almost a fog. The temperature was about 105F. Soon the “check engine” light was blinking and the engine seemed to be skipping/misfiring. We were going uphill, and as soon as we got past the haze, the engine went back to normal. Has anyone else ever heard of a problem like this? Could the weather really affect the engine that way, or was it something else that merely happened to coincide with the strange weather?
FYI my car is a 2001 Isuzu Trooper, V6, fuel injection etc.


They are great entertainment, the one silly bugger lives in a culvert under the path going down to the beach. One morning we get down there, silly guy sits outside the culvert, a snout full of grass he had collected. Looked at the dogs - they are always on the lead in the park! - as if to say “Well, fancy that! I’m working and you guys are idling!!!”
