wassup guys, I swapped in a B series into my EK. I have been noticing that under about 1,500 RPM, it bogs down considerably, then when I give it gas, it jerks me forward kind of violently. The clutch has a good amount of life. I cleaned the throttle body, IACV, checked TPS, all that stuff, any advice is appreciated. also I have noticed that when I downshift or press on the gas pedal in a higher gear, I hear a popping sound of backfire coming from the intake, am I running too rich? thanks a lot guys.

 

ECU?

Timing?

CEL codes?

 

running a OBD1 P75 with a jumper harness. timing is dead on, just did it while replacing the timing belt and water pump. I have a CEL, I need to get a paper clip and see what it throws.

 

What engine?

Ignition timing?

What codes?
