I just got my car running after adding the whole MP setup(except the ic, I made a custom front mount for it),42lb injectors, 255 fp. but now I am getting codes 998,113, and it idles at about 2500 rpm.
I checked all over for vacuum leaks and cant find any,checked the tps to see if it had the right voltage and its set at .5 at idle, and also changed the iac which helped until I stepped on the throttle and it went right back up.
Do I need a chip to get it to bring the idle back to normal and will it solve the code problems?
