i just did a swap on my ek, its pretty much a si swap but i have a gsr block with a 99 si head, the block is a 95 b18c1 with 99 internals and i'm using a chipped p28 as for now the car is running ok just the only problem is when it hits 1500 rpm the idling goes up and down and i would have to add gas to alleviate the problem. what could this be any help would be useful thanks.

I have the same problem except it idles at 1500rpm. When I first put on the head, it idles at 1500. Then I plugged in the ITR ECU and it jumps up and down from 1300-1,600 constantly. My friend told me it might be that the ECU is giving out too much fuel/air. It doesn't really bother me anymore, but I would also like to know how to make it stop.

I believe the problem might be the IACV. I have the same problem, but it's only occasional and onlyon start up..after about 30 sec. - 1 min. it's fine.

hmmm. maybe its the ecu because i have a p28 chipped with civic type r program but still its annoying not only that but everytime i shift gears it seems like the car is bogging, could it be running lean or rich i dunno please help out. thanks

joe pagolac

since type r ecu runs rich could this be the cause for the motor to run bad??? any help would be great.

It might be the sensor just right under the throttle body where the coolant go through. Remove the whole sensor. There's a piece of metal plate with 2 screw hold it in. Inside there is a white plastic screw, it might come loose.

Take off your intake and inside the throttle nody there will be 2 holes plug them one at a time with ur finger and if the bad idle stops when u plug either then the sensor that the hole goes to is the one that is acting up.( the Same thing happend to me)
