rough idle crappy preformance!!!!! need help

Also would it be better to buy an aftermarket cold air intake since i have an aftermarket header? Just asking.

If you are asking if getting an aftermarket intake will fix your issue, then the answer is no. Unless there is something wrong with your intake now.
 
Ok so i just cleaned my iac valve and that vacuum solenoid. Im hoping this was my problem. Ive done everything else but put a new motor in it lol.
 
Well did all that for nothing. Still feel sputtering when trying to go more then a 1/8 throttle. Any ideas?
 
Could sparkplug gap cause it? I read .045 and now just read .023-.031. Any thoughts?

How old are your plugs? And why has the gap shrunk, under normal operation, the gap should only increase in size from what I have seen.

Definitely set the gas to 0.044", but weren't they that size since you just replaced them?
 
I read that they are sapose to be .023-.031 and that was from mazda speed. But on a some weird websight it said .044
 
Your best info is in the glove-box,...
