i think my injectors are retarded, when the engine is between normal running temp, and normal air temp... like when it sits for like 3 or 4 hours, it starts so fuckin rough. it almost wants to stall for a couple of seconds.... but when the engine is cold, it starts perfect, and when the engine is hot, it starts perfect... this is so annoying and looks bad when other people see it... SO, when my friend puts his det in this winter, should i swap out injectors with his de?? i was also thinking about swapping the timing chain tesioner... anyone got any responses??

Before my #3 injector went, i noticed sometimes it ran a little rougher than normal on start up (occasionally) then when it finally went on me #3 just stopped firing.

Is it more a noise though? *** my NX will be a little noisy, but not rough on start up I've heard a few people mention this before.

nope, mine doesn make any noise, except the belt squeals for a split second when the rpms are around 500.... i wish i knew what was up!

This may be a dumb question, but how old is your fuel filter? Thats the cheapest and first thing to check if its a screwy fuel delivery problem on start up.

or

Possibly a sensor is telling your car its colder/warmer that it is when its luke warm and your getting the wrong fuel/air mix?

i replaced the fuel filter not even a month ago! ugh!
