Swapping MAF makes no difference... unplugging it doesn't seem to make a difference now either. Not throwing any codes in the DME right now while it has the surging idle from 1,200 to 1,500 rpm. It surges like this for a few minutes and then settles down around 1,200 but as soon as you blip the throttle it goes back to surging. What am I missing here? DISA, ISCV, MAF, all associated gaskets are brand new, I removed the throttle body itself to inspect it, replaced its gasket, I put all of that stuff back together twice and triple checked every connection. I replaced the vacuum caps on the back of the manifold. I've visually inspected all of the vacuum lines that I can access but I can't imagine that any one vacuum line could be causing this kind of problem anyways.



Crazy that when I pull the trigger on the parts cannon to solve a minor problem, I end up with even more and bigger problems.
