Well this doesnt seem possible?
To start off the cars a 95 200sx se-r. Avenir swap, fmic, n60 maf, calum ecu, other little stuff that's irrelevant in what im about to say. Ok, so lastnight I drive the car to my friends house cars running perfect (aside from the fact that my tps sensor is unplugged due to a screw wiggling itself out and the car being impossible to drive while it was still plugged in. Its been like this or maybe 25-30 miles) but still no bogging missing or anything of the sort. I'm inside the kids house maybe an hour or two and when I go to leave the car wont start. Turns over a whole bunch but seems like its not getting spark due to a strong smell of fuel. On my third attempt the car starts up but very choppy and sound like its missing. I decide I need to get the car home because its doing me any good here. Car gets home doesn't stall, choppy down low but seems ok above 10psi of vacuum.
Today.
I go to start the car and it turns over real quick then dies. Try it again car starts up but is running horrible again. Pop the hood fuel pressures fine, I notice another bolt has came undone this time from the turbo to the j pipe (which every time one thing goes wrong I lose a bolt somewhere else to add to the headache) but it obv isn't that. The red light on the ecu when on self diag. mode stays off, solid when in the normal position. mafs not unplugged/ wires shorted. Pull plug caps to see if any cylinders are missing and sure enough cyl 4 is not firing. I can't even start to think of what could have happened when no one was in or even near the car for 2 hours. Anything will help me guys so thank you for taking your time to read this and let me know if you have any positive input. And yes im about to go try a different plug/wire and see if it works but im doubtful this will be the fix saying that when the cars revved it sounds fine after like 2500-3000. Maybe the knock sensors gone bad? Hence the being able to rev part.
