So I bought a 1990 GTR last week and I have been cursed by bad coils and plugs but got all that replaced and tested And all is good there. But the car is still running ungodly rich at idle and through the revs. It’s spitting out fuel right out the pipe. Car will back fire and so I looked into the MAFs and used a multimeter to check the signal wires and power/ground and I’m getting about 1.2V at idle (1200rpm) out of the signal wires coming back from the MAFs as well. But the weird part is I disconnected the MAFs and the condition stayed the same. Also I’m getting 0V coming off my TPS at any throttle position. I’ve heard temp sensors can cause issues but the car does it cold and hot so I’m stumped.Hope someone can help me thanks so much!
