my 1jz starts and it idles fine but sputters on rev-up ???
i think it's the fuel pressure ??? maybe
i have twin walbro pumps in tank where do i set pressure on the fpr 35 psi is not right
before i had factory LOOKING injectors but not for this engine there red idles high and rev's hard there to much fuel with the white smoke so i got the stock yellow injectors now idles fine but sputters with no smoke
yes i reset the ecu nothing

does anyone have twin pumps in tank and where is your fpr set at ???
some one said plugs so i am changeing them on monday
any other ideas

do you have a magnetic wrap for the twin pumps? they might be interfering with one another, try running just 1 see if it clears it up. you dont usually need 2 unless you are making over 500 hp~ usually...

first tlo86 and freshmaker thanks
i found and fixed the problem today
there were hks cam gears that came with the engine who knew they were there (took the covers off to change the plugs and i said let me paint the the covers and found hks cam gears )
i set them back to 0 setting and that fixed the problem running strong now
now to fix the 2 leaks i have and try to put this thing on the road
