poor idle and cel
 

so i bought a turbo supra m/t a summer ago. i fixed the headgasket and the car starts now but idles poorly. if i keep on the gas evenly it will bounce between rpms. on my super monitor i pulled check engine codes 22, 24, 31, 41, and 52. i never driven the car when it was in good condition but it feels low on power compared to my 2005 Nissan altima 2.5s. the car has 3" downpipe, hks blow off valve and the head is ported. i know code 52 knock sensor rewire.i just cant figure out the other codes.

They're all pretty self explanatory. Look here: http://www.cygnusx1.net/Supra/TechTi...ror_codes.aspx
