ok so in my b18c5 which i just finished rebuilding. it idles at 1000 rpms just fine but when you rev the engine lets say to 2500 rpm when the rpms start dropping back to idle they get stuck at 1500 rpm and starts to bounce. any ideas?
Tb gasket leak, iacv circuit malfunction (check wiring), check all vaccum ports and verify no leaks are present. Spray carb cleaner around all gaskets included in the intake system. If no vaccum leaks check the voltage on your tp sensor.
