Here’s the deal bought this 240sx redtop in november with a blown turbo. waited until february to install t25, then got the maf in march hooked up everything and started the car, started fine but idle to high so i adjusted the idle screw on the iacv and bleeded the the air out of the coolant and went down to 800-900 rpm. so i took it for a drive 1,2,3 any gear you put it in the car won’t go pass 3,000 rpm even when you rev it’s like when you have a 2 step (rev limiter). so pulled into my house turned of the car the poped the hood started it again it ran for about a 1 minute the all of a sudden **smoke** comes from one of the injectors and then engine dies and won’t start again. Could it be a bad injector or fuel filter is cloged. I would really appreciate if some could help me out or give me some advice on what to do I’m very lost 😕 and don’t know what to do thanks ---

Usually idle problems like that have to do with MAF but injectors smoking? Id try replacing said injector and clean up the maf a bit. Also did you correctly time the motor when you got it? ---

first thing check injector seal…also check compression and once the motor is hot open the oil cap to see if its smoking…guaranteed there are leaks somewhere. ---
