low idle when in park(a/t)

[SmashingDsm]

ok guys i have a 92 talon a/t has a big 16g turbo front mount and a 255iph fuel pump with dsm link everything else stock. my issue is when the car is in park and neutral it idles fine no surge but when i put my car in gear it drops the idle to 500rmps or lower sometimes its turns off. does anyone have a idea on what could it be ?

what did you do? swap tc? pull them hoses and make sure that pump is working....

i just added enough transmission oil in it and it worked. now i still have that issue i had about idle when in gear so I'm going to do a full boost/vacuum leak test again go through everything .one more question would the tps be an issue i have it set to what it supposed to be on dsmlink should i try doing it manually?thanks guys
