i have a 98 integra gsr... i had a skunk2 manifold and a type r intake cam in the car... we uninstalled both parts.. and put on the stock parts.... we got the codes 45 and codes 1... (system to rich or lean.. and oxygen content codes) found out that vacums for secondaries were wrong and that the secondaries were stuck open... fixed that problem... car was running great.... car drives and feels good.. but at idle.. the motor shakes and you can feel it in the car and you can see the motor move some... and its more that it should... motor mounts are fine... and then after a long period of idleing it will throw a code 1... oxygen content.... what could be wrong.. why does it run good. but yet idle werid.. any help?? things we could check for??
thanks for you help!

correction the code it keeps throwing is ... to lean to rich 45

 

May be the oxygen sensor.

Should be fluctuating between 0 and 1000 millivolts constantly with the car running. Under 30 cycles per minute, or a very low voltage mean the sensor is bad.

Your scan tool ahould let you read the data.

 

scan tool??? whats that? please explain
