Ok so im having many issues with my b18b dx eg... first at cold starts it would idle at like 3500 rpm until warmed up, It was throwing map sensor code 3... code 10 iat.. code 14 iacv.... 7 tps for awhile until i adjusted it... and 43 fuel system... So after a few days of messing with these sensors and testing them i figured out my problem to the high cold start idle.... the fast air idle valve... i opened the sensor tightened the white plastic piece and voila started it up and ran at 800 rpms.... after i reset the codes and ran it again it gave me all the same errors plus the tps 7 again... When i started the car this morning the motor went stratight to 800 rpms on a cold start.. now it wont warm up like its supposed to.. it bogs really bad down low still and keeps failing emissions cause of the high hydrocarbon output.. does anyone have any knowledge they can lend me?? i am getting ready to go buy a new map and o2 and see if that helps, but would like to avoid spending more money i dont have. Thanks.
