well here in Tn we've had some pretty crappy weather and today I was driving around and my 87 pickup with a 22r started bucking and when slowing down would try to die. It didnt do it when the engine was cold but after it warmed up. If I give it a quick rev itll die sometimes and I got it to backfire once. After it dies I have no problem starting back up like if I'm braking all I have to do is start it again and give it a little gas until I get going again. I have checked the AAP and there was no fuel in the vacuum line. I read that it could be the Idle cut solenoid. Just looking for ideas on what to try. I just put on new plugs, wires, rotor, and coil about a month ago. talked to a mechanic and he said it might be carb icing sense it is barley in the 20s and we had almost 90% humidity today dont know anything about it but just add it to the pile of reasons.

 

Are you still using the stock air cleaner ??

I have seen so many aftermarket air cleaners freeze in conditions like you describe.

 

First thing I thought of is carb ice. The right conditions for it. And as Wyo said aftermarkets can be prone to do that.

 

No it's a after market one with the stock carb

 

went and did some snow wheeling this morning and had no issues.

 

Never had a problem in alaska with my old 84 with the stock air cleaner and preheater tube..

 

The whole issue was really weird but I've been out and about for the past 4 hours with no problems

 

If there is no heat going to the air cleaner and now it's fine, I would say you had carb. ice.
