E=MC^2

it has 143k on it its got a new maf meter and intake i replaced the maf because it use to idle like crazy after i replaced that it ran perfect for about a month now when im going 35 and hit a red light when im slowing down the rpms bounce from 5 to 10 usually untill i stop then it doesnt happen or sometie i put it in neutral then back in drive and it idles like normal. any ideas?

also my gauges are all slow to do anything my speedometer doesnt catch up till im usually going 20 to 30 at worst ive gone all day without it moving at all. that was a cold day so im sure the cluster being freezing cold didnt help. any ideas/feedback is appreciated - Brian
