Aftermarket Intake System
go on ebay and get one for 25-30 depending on your year, just a simple short ram, then bring it down to autozone, and get a k & n to fit.

traced out ecu, no shorts, everything is connected. I also went ahead and replaced all of the connectors on the sensors, and all the injectors. still no change. Timing is set at 10 degrees btdc, also put iridium ix spark plugs in.

79 280zx engine problems.
ok so i got the engine to run good, no more erratic shaky-ness. only issues, on cold start, like sitting for more then an hour or two, when i start it, the engine idles up to 3500 rpm which is bad and dangerous. also, it stalled out a few times. it has new fuel in it and a fuel system cleaner as well. Also, i can start the car in drive, which i've heard means somethings not right.

just replaced ecm, no change

Brake lights won't go off
just tape a quarter to the hole at the switch, that should keep it from staying on when the break pedal is stationary.

wies are good, just for some reason its not making a connection with the 4th injector, I removed the vlave cover today to check the timimng chain,. its good, valve clearence is also ok, maybe a thousands of but thats ok, wont effect performance, was quite alot of sledge build up, some the size of base balls, and hard as a rock, going to do a flush, but still trying to fiugure out the running rich and erratic idle. what else should i check. also replaced the coolent temp sensor.

well i replaced the number 4 injector, since it was cracked, and leaking, making it run rich, replaced it and its still running rich. so i pulled the wire conenctors on the injectors one by one, only the 4th injector showing no change. I used the bulb tester to check for current and pulse of the injecotr cables, all of them light up. Could they have sold me a faulty injector?

having an erratic idle, running rich. ok so i cleaned out intake manifold, put new gaskets on intake manifold/exhaust manifold, all the way down to the cat, throttle body gasket, torqued down to spec. refurbished afm, new fuel pressure regulator, new distributer, wires, plugs, fuel filter, cleaned egr, new air pressure regulator,new pcv, new injector because one was cracked. Tested coil, spark is good, it actually went arced up to 40. set static timing to top dead center and timing to 10 degrees btd. so heres the bad, im having an erratic idle, it stumbles and doesnt hold steady, lack of power, and after i take it around the block once it shuts off and has problems staying on. Also the fuel pressure at idle is 35 psi, the book says its supposed to be at 30, and when throttlke is fully open it jumps to 40 psi, the book states its suppposed to be at 37 psi. Also, i did a vacuum test and intake vacuum is really low on the gauge, it says late valve timing but i think thats wrong. its running super rich, gas is dripping out of the exhaust and carbon is getting sprayed all over the cement. I really need help on this. p.s. also if you guys have pictures of the vacuum lines and the electrical hook ups in the engine bay that would be really nice. just to make sure everything is hooked up properly, pretty sure it is though, but just want to double check.
