b16a2 in ek, engine surge, please help...
ok i have a 96 civic cx running a 99 b16a2 with the 96 cx harness and an obdII p72. The car idles fine and the wiring is all good. The problem is when i hold throttle down a tiny bit, as to keep the rpm's at 1500 or 2000, the engine surges from like 1400 to 1800. it doesnt do this if i push the pedal down farther. This real annoying like when im in traffic or trying to go slow over bumps. anybody have any ideas?

i had the same problem with the same swap and chassis. except i was using a p73. it started to happen out of nowhere. what i did was unplug/pulg the ecu, then took off the neg. on the battery to reset the ecu. the problem dissapeared. GL to you

could be as simple as your ecu needs a reset, that or there's two little bolts that go on either side of where the throttle cable bolts to the bracket on the intake mani, take a look if there's a gap, then that "Surge" you speak of could be one of the boltsgoing from crooked to flat on the bracket

I reseted the ecu 3 times and it still surges. The throttle cable is bolted on tight too. I noticed that it doesnt do it until the car has been running for about 15 seconds... could it be a bad sensor? the cel isnt on either.

Did you bleed the air out of your cooling system??? I had a slight idle surge on my car when the first day after swapping and it was because I had alot of air in my coolant. It's not common, but something else you could check.
