Sharp popping from exhaust
The last couple of times I have started the car and begun to drive I fell like it is hitting on 7 cylinders at low RPMs (<2000) and I get some very sharp irregular popping from the RH exhaust when I accelerate. After the engine gets the least amount of temp (in as little as 1 or 2 a minutes) this ceases. I am inclinded to think there may be some debrit in a fuel passageway that is intermitantly blocking the idle fuel jet. #1 cylinder seemed to be the least affected by idle mixture screw movement. I pulled the idle jet and it was clean.
Ideas??
