Ok I swapped my intake manifold and throttle body, replaced my stock intake and throttle body with AMS intake and a GSP throttle body. Had some high idle issues, disconnected the battery for a bit, came back and still a little high and kinda running rough. I checked on evoscan and TPS was at 13% and would read 100% when pedal was pressed. But now it won't start not sure why? All connectors are connected and secure, vacuum lines are on and secure. I did tie some vacuum lines into each other wondering if I shouldn't of done that, anyone agree?

If any one has some insight or directions to point me in I appreciate the help!!!

 

Have you looked at any vacuum line diagrams?

 

Yes. After work tomorrow I'm going to go get another nipple and get the vacuum lines each it's own port and see if that helps. I did cap off the lines to the egr solenoid but don't think that's the issue.

 

You need a tune

 

I was thinking it might need adjusted. My car is tuned already but thinking it might need tweeked with this intake

 

is it stock or 65mm+?

 

70MM throttle body

 

FYI got it running good again, the throttle body was junk wouldn't idle right, swapped my stocker back on and it's good. To be honest I thought the GSP might be good bang for the buck but it's not. Spend your money on something little better, ported stock or get name bran aftermarket.

 

glad you found the issue, smart to swap out to your stocker. I see alot of people running big numbers on ported stockers

 

Had the same issue yesterday. These TBs arent worth a F. They boast about direct bolt on and no modification needed and all that bs. I read somewhere the EVO X comes with a heat activated IACV instead of coolant. But regardless, the TB was connected EXACTLY as the OEM TB and mine idles at 3k rpms. FML. Now I need to replace the shaft seals in my stock TB because if I go WOT the butterfly sticks open and I put everyone on the road's life at risk.
