heres a part #2 to my stupidity so im curious if there linked.

where the fuel first enters the rail, cyl 1 an 2 are fouling really quickly with carbon, cyl 3 is clean, and cyl 4 which is farthest is looking lean.

now the question, if i had a fuel leak on the end of the fuel rail, not the fpr or gauge port, would that have the pressure gauge read wrong? *installed next to fpr* and actually have higher pressure entering the rail and then fading out across all 4 injectors?

fishin for answers b4 i start messin around tmrw. just a idea im dancin with atm lol


******* leak at end of rail through gauge off which is inbetween cyl 3-4 so cyl 1 and 2 were running higher ps then needed which fouled the plugs

 

not sure what kind of car you have but if it has egr you should clean the ports and the valve

 

only thing iv touched before issue was fuel rail/fpr and only thing i see wrong is a leak at the end of cyl 4 aka farthest away from where fuel enters

since u ask bout egr, technically i had 1 even though it was nvr plugged in and i deleted it when doing manifold swap. ur basic n/a b18 ls build thats been pieced together part by part lol

 

if you had fuel leak it would smell very much, so i think it is difficult not to understand it. This that you are facing is common to all one throttle and 4 in line engines. its not enough air the problem (due to limitations at one throttle and inlet manifold design) and not the fuel.

 

personally think i have too much air no offense. 70mm tb port matched to skunk2 manifold. reason the fpr went on so i can mess around since im still obd0

and the fuel leak is ever so slightly, but it might be enough to **** up wat i did. waitin 4 rain to stop so i can go mess around
