can somebody help

[projektS13]

my car wasn't runnin right a couple of months ago it would lose rpms after driving it awhile it would drop down to 9,8,700rpm,etc and i would rev it up a bit to like 1500 and sometimes it would be ok and other it would still go back down until i wold drive. i replaced a couple of gaskets that were blown incl.the exhaust mani that was warped awhile back and it fixed the problem for a while.but like a month later its doing it again now.is it the same prob?also at first it will boost to about 7lbs. after drivin it for a good while it just feels like it lags and barely gets to about about2-3lbs. it will happen somedays other times it wont. whats like a normal idle level for the sr mines at about 1500rpm. is it a boost leak or is it the turbo itself? like i said it happens not right away usually after i drive for awhile. usually when im like at an incline it too starts dropping rpms.when i turn the car off and start it up again sometime also its low in rpm. so i rev it back up to idle and it good..most of the time. does anyone know what it is? please help.thanks

ive had that problem befor in my civic. like when it gets hot it just runs defferently or weak. is ur check engine light on? or do sr's not do that?

check your wastegate unplug it and see what it boost at , and check you ecu for codes if its a red top theres more but im tired ill update in a bit

[killakingquan]

also surging idle may be due to a bad coolant ecu sensor or clogged iavc

well if you unplug the wastegate dont launch the car , cuz if it is good you will boost crazy ammounts and mess up stuff , but thats how you know its working , also look at it , ryan had one where the rod was bent ,

for the ecu if its a red top then there is a red led next to the screw on the ecu , you can use that to check for codes , then look up the code on the net , look up sr20det codes
