Got a new problem today, input please
Today I installed my FRx, and HPx. Went very smooth. The square head plugs came right out, no problem. I happened to have a square head 3/8" drive socket, so lucky me. The hardest part of it all for me any way was just grinding that little bit down because it's a e99. Installed the recommended GOLD spring. Took the opportunity to paint the tubes and spyder as well. Got it all back together, checked for leaks and took it for a test drive.
Fuel pressure is up. Was 70 idle, 65 wot, now is 76 idle, 70 wot. Is this ok or too high? I can put the lighter spring in if need be.
The real problem, the truck was bucking hard under throttle, and then I pulled into a lot to double check for leaks, and it wouldn't restart. Took about 5 mins on and off cranking to finally start. Then on the way home, no more bucking. My gut says CPS, but I wanted some input first. I have never replaced it, and I know ford has never done it.
Is there any way to test for a bad CPS, other than to just put a new one in? Also, I recall there being a gray, black and I think blue one. Is one better than the other, or what?
Edit: here are some pics to help you think!
