Well I tested for leaks and found a tiny one on the air regulator, got it sealed up and no difference. I'm looking for an oem z32 maf just to rule that out, there are no 300zx cars in any junkyard near me. I got new plug wires as my other ones were in bad shape, no difference. Cleaned the rotor and cap. Ive noticed that if I unplug the tps it will idle worse but has better throttle response. Checked the tps and it still reads .48 when closed and slowly and properly raises to max voltage (can't remember exactly number but it's working correctly) only thing I can do that makes it run better is add a lot of unmetered air, or take the maf off and press it half on, half off the intake pipe. Seems to idle much better like this and has better throttle response. Also I noticed that cylinders 3 and 4 seem to have a far lesser effect when I pull the wire or injector than cylinders 1 and 2, like it's running on 2 cylinders. Also all 4 plugs are a dry sooty black but cylinders 1 and 2 are tan on the ground electrode. I have tried switching the injectors 1,2 with 3,4 and there was no difference. Plugs and wires are new, egr is deleted. I dont know why they would burn unevenly. Maybe the cas is halfway faulty? Is there a way to test it?
