i posted this in the hybrid forum. but theyre not much help. maybe you can help.

i just recently swapped my gsr with a jdm b18cR. but ever since i got it in its been acting funny.

lately ill be driving along and ill be coasting up to a light so i pull it out of gear and coast to a stop. but while im coasting my rpms jump to 2800-3000. and hold. they stay there until i come to a complete stop. even then the rpms only drop and idle at about 1800. way too high. this comes and goes.

other days after driving it for about 20 minutes it decides to bog really bad. ill be driving along and decide i want to pass a car so i give it a little gas and i hear the tb opening up but the rpms dont go anywhere. i go wide open throttle and all it does is creep (about 100 rpm in 10 seconds).

and also in the morning (everymorning) when i pulll out of my garage, when the car is still cold, when i turn i hear a whirring/rubbing sound. but its not wheel rub. and to add to that sound i hear a loud pop that sounds like its coming from my axles. but both axles are brand new. my axle seals are bad i know that much. i orderd the parts from honda. im hoping that will for some reason fix that.

any help would be great.

 

I did the exact same swap for my GSR, and same thing is happening to me for the idling parts, where it would Idle high until its completely stop, and the charateristic is different with different kind of driving, such as driving the car hard, driving on the freeway for a long time, or just local, the rpm acts differently accordingly,

Recently, my idle have been going up and down and up and down when the car is moving from 800 to 1700, its weird.

For all the people thats saying its normal, I dont' believe because it not acting normal, Honda would not sell a car thats like that.

 

this acted the same way when it was in my old car too. but i agree this cant be normal. especially when it only does this half of the time.

 

the only clue i know is that, it does not do it with my Apexi Power FC ECU, so what could the Power FC overwrites?

 

anybody have any input?

 

bump

 

i know this may sound crazy but my 94 si vtec did that when i swapped the h22 in it...

i unplugged the plug to the egr and vaccum line to it and now it runs perfect but with a cel....

i replaced the egr and now everything is great!!! hope this helps

 

Do any of you have ITRs?

did you check the igniter coil?
