Fuel stuttering

[Jdam15]

Ok guys I need help. My 91 eclipse gst fwd, is acting like the fuel is clogged. Mostly happens when the motor is warm. I have checked for water and changed the fuel filter and put fuel system cleaner threw the tank. And still is doing it. I have a new pressure regulator coming in today. But does anyone have any other things I may have missed?

I would do a pressure test on the fuel system

I have a new walbro 255 pump. That I havent installed yet. But ill do a pressure test.

What do you mean acting like? What is the specific problem? No power? Misfire? Backfire? You may be chasing the wrong system. Tell us specifically what's happening and under what conditions

When im in second gear at about 2500 rpm it starts to cut out like loose power. It feels like bad gas or even injector problems. Even if I romp on the gas it will do the same thing and at high rpm it will back fire sometimes

Do you have a way to log? Have you checked the usual tuneup items? Is it loading up on fuel and rich? . Overheating? Have you done a boost leak test? Have you checked any sensors or harness connections?

I have gone threw and done all the tests and leak tests. I am missing the cones out of my intake. Done all my tune up things and even had my brother look it over, he runs a 1500hp talon I trust his insight, hes gone and I couldnt get ahold of him. Sorry no way to log yet.

Has car always ran this way? Any recent changes?

 

[Jdam15]

I have done nothing different other than fix all the leaks and turbo leaks.

 

[pauleyman]

2500 wot or just driving normally. Have you tested any sensors? Opened ecu? Did it just do this all of asudden or gradually got worse?

 

[Jdam15]

Either wot and driving normal, its gotten worse I havent messed with anything other than the fuel filter and tune up
