so ive got this 89 toyota that i just rebuilt the motor in and got it all installed and running, and it actually runs really good, has plenty of power, but at idle this thing will load up pretty bad, ive replaced the TPS because of Error code 51, ive now got the timing set just right at 5 deg BTDC, im new to EFI and toyotas and im running out of patience. By the way, the Intake plenum is completely coated with sooty black carbon crap....not sure what to do here, any help is greatly appreciated, im sure its something simple but its getting frustrating.
