Ok well I got this bad idel problem. (like 2200rpms) Before i left for a test drive fule pressure was flickering from 36 to 40 nothing steady. The car does feel reel good through the mid range at all. Top end feels kinda good. But then the power fell all pretty good so i get out to check areound and the fuel pressure is at a steady 22psi . (I have a aromotive and gauge) So i cranked it up some more just about all the regulator would go and got about 30psi and drove home. i check for kinks in the fuel lines but did not find any.
Any idea what i can check.

 

Maybe bad fuel pump, low voltage to pump, bad fpr?

 

to all that, especially bad fpr, I'd also like to add filter to the list though, but I'm leaning towards fpr..........
