Hesitating only when warmed up
I have a 97 Chevy Suburban 5.7l, 170,000 miles.
I just replaced the spider injector with the new Delphi design. It fixed the hard starting issue it had, but now when the engine is warmed up it starts to hesitate and stumble. If I am really easy on the accelerator its not as noticeable. My question is would a worn distributor cause this? I have replaced the cap and rotor, plugs and wires, and most of the other sensors. If any one has any ideas of what it could be please let me know.
