Ok i've swapped an s13 black top SR20det into my Datsun 510.
The motor will just not hold an idle after the engine is warmed up.
Things ive done.
Cleaned injectors, replaced the seals made sure they are not leaking checked visually with the fuel rail out of the intake. no leaks
Cleaned the IACV THOROUGHLY tested each solenoid with a 12 volt jumper. They are moving, replaced all new intake gaskets and IACV gasket and verified the black/yellow wire gets 12 volts.
Tested the TPS circuit wiring signal wire gets 5 Volts with key on. Checked the TPS sensor for OHM levels they are within spec. Adjusted to .5 volts when throttle plate is closed goes to 5 volts when open.
Fuel pressure is at 43psi.
Mechanical timing is set dead on at 15* TDC Ignition timing is set at 15*BTDC. But the only way to get it there was to set the CAS full lock to the right, it was set in timing mode with the TPS unplugged at 850 RPM.
After plugging in the TPS and engine is at temp it will not hold idle. ill post a video of it. IN THE VIDEO the TPS is hooked up after timing was already set in timing mode.
MAF has been cleaned with MAF cleaner
Ran a boost leak check no leaks could be found all vacum sources are plugged or sealed.
E5 ECU only code I get is 55
New NGK copper spark plugs .034 gaped 7 psi boost T3 turbo
