If I was you, look up my recent posts on losing power and see if you can get any ideas from it. Or give us alittle more info and I will do my best to give you some ideas.

Posts: 1928 | From: Vallejo CA | Registered: Mar 2009  |  : Blue92 ¯ Member # 8789 posted                              Shouldn't. Also when my car was doing this I had a bad spark plug wire or wires. They were brand new wires with only a few miles on them and the heat from my headers got a hold of them.

Next I would follow some of the previous advice to reset the idle. If you haven't done a tune up (ie plugs, fuel filter, dist cap, etc) I would do that first. Also, check your plug wires to make sure they are in good shape and not burned. Those are the simple and cheap things to check.
