I think you will be better off just trying to get your injectors. No kidding i went through the same problem and sure enough got some used ones, replaced them and now the car runs fine. No rough idle any more and not start up problems.

 

ok, well i replaced the injecpotrs and everything was fine for a week. now it looks ugly. hard time starting and it would stall at idle or when i come to a stop. got it checked out and there was fuel in the crank case. drained the oil like water (in this case black fuel). not sure where the leak is coming from. any ideas?
