i just swapped a 94 LS motor into my coupe... now the thing turns on but the problem is it idles around 1 1/2, idle is constantly goin up and down, when i go to take off the engine bogs out like if it wants to die down but then when i hold the gas pedal it gradually catches up and once it reaches about 3 1/2 - 4 thousand rpms the motor opens up to full power! the engine is a complete 94 LS with a B16 tranny! everything on the engine is OBD1 but the harness... the harness is a OBD2 that we converted to an OBD1 (meaning we changed the alternator, dizzy, and fuel injector plugs) car sounds fine n feels strong but its still loosing power, can anyone help me!
