Ok well when I start my car up it will die instantly unless I give it about half of the pedal. When I press the pedal it is very very choppy then after about 2 minutes the rpms will shoot up to about 3500 or so and then it will run fine. After that I can turn it off and try to start it again and the same thing happens over and over. I just replaced the pressure regulator cause thats what I thought it could have been and it didnt help. I have also installed the new 30# injectors and a new fuel filter and it is still doing this. Any ideas guys??

 

What all do you have done to the car? Did you get the ecm tuned for the bigger injectors?

 

Sounds like an open loop tune issue

 

my brother was having the same problem with his 94z and he spent a lot of money. the problem ended up being the ignition switch on the column under the dash. the part cost about 12 dollars so its a cheap part and could fix the problem but if not your not out a lot of money.
