Well it's been a long time coming but I have finally had some time and some extra cash to pick up a few things. I picked up a scanner and fuel pressure tester recently and this is what I have come up with.
I keep getting the codes for misfire and running rich. I cleared them out only for them to reappear.
Yesterday I changed the plugs and wires again. When I removed the plugs, they all had a pretty strong odor of gas on them. I don't remember if that's normal or not. This still didn't help the situation of the car hesitating when I nail the gas.
Today I hooked up the fuel pressure tester. With the ignition turned to ON, I was getting a reading of 43 psi. I tried this a few times and I kept getting the same reading of 43 psi. Then I started the car to see what the reading was when the car is running. Now the guage needle is vibrating between 78 psi and 84 psi. I shut the car off, drained the fuel in the tester and tried again. As soon as I start the engine, the pressure goes right up to 78 psi and 84 psi. I tried to rev the engine a few times to see if it would come down but it stayed with the high readings. The car rightnow was cold since it sat overnight so it is idling a little higher but if I understand correctly from what others have said on this forum is that the pressure should ALWAYS be between 40 and 50 psi.
Does anyone know what would be causing this high pressure and hopefully be causing this entire headache?
