I thought my 4runner was just in need of a tune up but when I went to change the filter I noticed the line coming in was twisted and pinched almost shut. I just bought it and from the beginning I could tell it needed a lot of pedal to go but it still ran good once it was going. Could this be causing that much of a loss of power or are all 2nd gens with the 3.0 underpowered. Also would it be possible to cut the metal line and splice a rubber line in the middle...Thanks for any help you can offer
