i just ran a pressure test on my 98 neon 2.0 SOHC and it was @ 50psi. i have been having trouble with misfires. is the feul regulator/filter the cause??and do i have to replace the one in the tank or can i put a inline regulator and filter to bring down the pressure. and would a CAI have anything to do with that high of pressure.

 

50psi isnt really high.....stock pressure should be right around 48psi

 

i thought neons dont have filters? one dayi went to autozone for my 97SOHC and they said theres no filter for them. they said its a one time thing.

 

should the needle on the gauge be steady? or shakey

 

the filter is in the tank connected to the pump and combined with the regulator

 

fuel psi gauge?

mine twitches very slightly at idle but its because Iam running big injectors......

 

yea a fuel pressure gauge. and mine goes from 40psi to around 55 psi back and forth real fast.

 

50psi isnt high at all. you have a fuel filter/regulator (yes both in one piece) mounted on your fuel pump module and a fuel stainer mounted on the end of the fuel pump. just i case your wondering.

yes but not necessary


no.

if that's your car in the sig that would be a warm air intake.

.EDIT. this link gives all the info on the fuel system

no my air filter is shielded from the header and block,it gets good cool air.

 

it may be shielded from the header and block, but the air in the back of the mtoor still gets heated up pretty good.....you wont have a real cold air intake unless the air filter is in front of the motor
