P0505 CEL 97 Civic Ex
So i have a 97 civic with a jdm D16A & the crank sensor has been jumped at the ecu. Got car out of shop in march for the motor swap and she ran good for around 3 weeks but rpms would dip almost to 100 when clutch pedal was pressed in coming to a stop. Then CEL for iacv so took old one off and replaced it with brand new one. Took throttle body off cleaned all ports & intake best i could but still P0505. Was a valcum leak from pcv so new one valcum leak gone. Car will hunt idle from time to time & rpms dont drop if iacv is unplugged but jump to 1500rpm when reconnected then @ 1700-2000 motor would jerk / sputter. Its like not enough fuel or air , rpms will go up & down when its doing this. Im stumped and it seems to only be getting worse & doing it more often now. Oh btw the tps checks out good & iacv shows 14.3 on multimeter with key in position II & car running. Please Help!

Re: P0505 CEL 97 Civic Ex
The shop was going to charge me $75/hr to figure it out. If you cover the little port inside the throttle body while its idling it will go dead. Before i replaced the pcv it would just idle down really low. Ive gotta be on the right track making some kind of progress with this thing atleast i hope. Could it be the ecu controlling the ivac? Are the rpms suppose to drop to 600 with the a/c on?

when i tried to bleed the coolant system the fan would kick on & coolant level would drop so topped it off & small bubbles over & over its like they never end. Also just installed a crv cluster & temp needle seems to be a little higher when running than the stock civic gauge needle. Maybe bad temp sensor?

sounds like tps! maybe my 93 civic ex with a d16a, did the same thing between 1500 and 2000 rpms, rpms could vary test before replacing though to save money
