I just got done putting a d16a6 into my 90rex, and the engine doesn't run right. I step on the gas and i get a huge hesitation, it revs a few thousand rpms then hessitates again. My ecu throws a 1st cylinder position code and i have no idea how to fix it (since i had a 1.5 mini-me prior to the 1.6.) could this be why my car is running like crap or could my timing be that off?


ecu codes....
9-1st cyclinder position
10- intake temprature
14-eacv
