I changed my plug wires and cap and rotor and my car idles rough and when its in gear idles REALLY rough and feel kinda like its gonna stall.. what could the problem be.

 

You probably mixed up two of the plug wires.

I thought I told you to take off one wire at a time and then put it back on with the new one so you wouldnt mix up the wires. Now you have to go back and make sure every wire is in its correct place. The firing order is 1-8-4-3-6-5-7-2. plugs 1-3-5-7 on the left and 2-4-6-8 on the right. Instant message me again later and ill try to help you out.

 

Yeah, look on the intake manifold for the firing numbers for the engine block. They will be engraved on the intake. And the firing order on the dist. cap goes like what Tom (COBRA) said.
