No power under load while on petrol
Runs fine on gas.
Petrol it's like it's starving for fuel under load. This problem has always been there, but seems to be getting worse. I have changed the fuel filter and have pulled out the vacuum hose off the fuel regulator and that was dry. I don't think it's injectors as I ran a screwdriver over them and can hear them clicking, I disconnected all of them but the last 2 one at a time and there was a noticeable difference which there should be. no black smoke at all. I know that these tests are only basic, but that's pretty much all I can do at home.
Starts and idles fine. Fuel pressure should be the same at idle and while under load, yes.
Fuel pump is in the tank? How would I go about checking it's working correctly and what else can I check..
Thanks all.
