Codes IO39 is a trans code for the torque converter
code EO52 is your Idle circuit, TPS out of wack
You need to clean out the throttle plates and egr passages, Take off the air cleaner and look down the throttle plates by opening them up(motor not running). All that black junk needs cleaned out, there are a couple tubes down there also, there for the EGR valve, make sure there not pluged also, clean out with a coat hanger and carb cleaner. A TPS adjustment is needed after that. You need a special wire assyembly for this, so you can put a volt meter inline with the TPS to set throttle angle for Idle and TPS voltage(.5 Volts)
do the cleaning first then do an idle relearn, which is, warm up engine first, then shut it off, cycle key 3 times (off posision then to the on posision 3 times), run car for 3 min with no heat or AC on, then turn on AC, let run 3 min, then with foot on the brake put it into drive for 5 min still with AC on. Shut it off and restart engine see if this helps it, if not TPS will need set
I dont remember what EO96 is, might be the EGR, The tubes may be pluged
try this and let me know!
