I just installed a new megan fpr in my ca18 240 because ive been having fuel related issues… i started the car and the guage stays solid on 40psi then my idle starts to kick up a bit then the guage gets jumpy between 20-40…i also just put in new ngk iridium plugs in and a new fuel filter…it sputters pretty bad at WOT … anyone know what would be causing this?

thanks

you need to gap your plugs.

Be careful when gapping iridium plugs though.

i did gap them to like .30ish though? even if its slightly off would it cause that bad sputtering at full throttle?

Is the pump new? You shouldn’t get less than 10psi of your base, at idle.

if its the fuel pump ur talking about then yes its about a month old walbro 255lph… talked to autodream and the gapping specs i was given for the plugs on here were apparently incorrect so that should fix my stuttering problem then my ecu’s going down there tomoro so i’l see what happens!
