I am working on a buddies car and got everything in. Reused the single cam injectors, a obd1 b16a harness and distributer etc.. got it running... the idle is kind of rough and when you give it some gas it sounds like a Subaru. Its wired correctly, no codes etc.. I changed the Tbelt with the motor out everything was on time when I put the motor in.. Does anyone have any ideas to why it could be running rough?
Anything would be appreciated...
Thanks!
