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!

have u double checked ur timing...
i notice alot of cars idle funny when timing is off, maybe check for vacuum leaks since you installed a new Intake Manifold...
good luck let us know how you go

 

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