Here's the scoop:
1. Codes P0300,0303,0304 All misfires cylinders 1-4
2. 1.2k miles on valve job, Brand new plugs, wires and coils
3. Slowly lost mileage on trip from 25 down to 20 and slowly lost power.
Things I've done:
1. Swapped out coils with old coils and wires. NO CHANGE
2. Changed fuel filter NO CHANGE
3. Changed fuel pump NO CHANGE
4. Swapped out injectors. NO CHANGE
5. Swapped out throttle body NO CHANGE
6. Checked compression 155-160-163-152
What it acts like is that it is starved for fuel...Doesn't really have a miss.
If you are idling and go to WOT, it sometimes will rev up to about 4k rpm and then stop revving, other times it will die like a car with a bad accelerator pump in the carburetor.
Next thing to change is the fuel pressure regulator on fuel rail.
Any other thoughts???
