Idle problem, makes my PRO 5 shake

[Bebotech]

So, my RPMs are lower than normal and I have replaced wires, plugs, and intake hose. It seems that it is just below the normal line and this makes my car shake a little. Can someone help?

You could seafoam the car and then change the oil and see how much it helps. Usually smooths out idle. Also check your grounds, poor grounding can cause slight stumbling.

Do you have a CEL on?

What do you consider to be the "normal line"? Proteges are supposed to idle around 700, but mine's been at 500 for as long as I can remember. Try cleaning the EGR valve and Idle Air Control Valve.

I thought the normal was 800. My P5 is at 700 but, is not rock solid is kind of shaky.

Can someone please tell me what CEL means? I am not very familiar with acronyms.
