Well my car was only running better when cold, but now it's the opposite sometimes. The other day it ran totally gutless when cold and when it heated up it started to run much better at times. The car is running rich all the time. I had someone stand behind the car and I gave it about 1/3 throttle and a little smoke came out. Past 3000rpm it feels like the car is over revving. Last night it ran like usual, gutless. I can think of 4 things that could be causing this .
1. Bad computer
2. Bad injector,injectors
3. Bad fuel pressure regulator
4. Worn out engine, time for shortblock
