i have a 95 240sx. the problem is it dies when the car warms up? when i first start it up in the morning it idle perfect for 10-15mins. after that it just starts to bog bad and then it just dies? .i did do a self diagnostic. and dosnt show any sign of electrical failure or motor failure.. i read the manual and did every thing i need to do for the diagnostic. shows nothing is malfunctioning. im kinda stuck at this point. Any info would be helpful.

 

check your injectors for leaks also check for vacuum leaks.

 

i would say its the catalytic converter. Whats happening if it is clogged or bad or whatever is, when the car first starts up, theres no backpressure in the system. As it runs, and the cat heats up, it creates more backpressure. Ususally this isnt a problem, until the catalytic converter gets clogged. Then it creates excessive backpressure and heat (which makes the air expand more) which creates so much backpressure the car will stop running. Im guessing that after you shut the car off for a few minutes it will run good for about 10 mins then die again? Jack the car up, take 2 of the 17mm studs out of the cat, and pull it down enough so that everything from where it used to bolt up is in open air. Start the car and see how it is... if you want to take a test drive, be sure to completely take off the cat... you dont want any mishaps.

 

lol its cool guys thnx for the help i just got my car back yesterday and was a bad distrubutor... its wasnt reading the fireing code and just went bad,... now it works good now!!! ... i would say now if it dies after warming up ... its the distrubutor or fuel supply or some sort of leakage in the pipeing system or something...



now i got another question!
would a jdm climate control work in a usdm s14? if soo what can i do...cause the wireing dont match up... do i need a harness and plugs. or would it work at all?

 

Its possible, but you need to make sure that if you do buy one that 1) you get as complete a harness as you can. 2) that all sensors are intact, or the automatic control wont work from what i hear, just makes it digital thats all.
