Hello I am new to this forum and I am looking for some help. I have a 1999 mitsubishi eclipse 2.0 non turbo. I had stage 1 crower cams installed along with new springs and retainers, I also bought 50 state legal pacesetter headers. After installation my check engine came on saying bank 1 is too rich, I also had a random misfire. It has a rough idle and sometimes the car feels like its going to stall. I went to try to get it smoged and it was burning too much hydro carbons. My check engine light only comes on like every other 3 days or so. I took it to the dealer and they did every minor inspection and could not figure it out because they didnt have the time to get really into it. Some people say its my cams, others say its timing, im pretty much clueless. Can someone please help me, Im going to need to smog it soon for registration and i want to do it legally if i can. Thanks

Steve

 

Well you cant just throw cams in a car and figure it to run the same. You are changing the duration of the cams so obviously now your letting in more air then it thinks. Its hard to say exactly why its giving the missfires though. Who installed the cams? Is the timing correct? Did you make sure all vacuum stuff is back on right
