Sorry I haven’t got back to you, I work late nights and sleep my day away…then repeat…

All of the cylinders check out for spark.

I’m going to test the fuel pressure tomorrow. Under a load the car loses power, then if I continue to increase rpm levels, it misfires. Slow acceleration in 1’st and low rpms of second, are fine, once a load is added the problems begin.

I disconnected the vacuum to the FPR. The engine ran exactly the same, only difference was I got the P0170 generic code, to throw the CEL. This was the code that would show pending condition, but not throw the CEL. I’m going to rent the FPR tester from autozone tomorrow, I got to work the graveyard shift again tonight. The only visual clue is that, the fuel consumption gauge, doesn’t drop under load, it hovers around 10mpg. What PSI should I have? I do have a Bently manual also.

I swapped that out with a new one, I had laying around, when I took off the intake to redo the vacuum lines and gaskets.

did you check the wires/engine harness or clips when you changed the cps?

it sounds like a problem mentioned in this thread
