OK so about 2 months ago I noticed my car started doing an odd sputter after I filled up with gas at a local gas station. I then put a can of "Heet" in my gas tank thinking it could be caused by water in my gas, didn't help so I put a can of seafoam a couple weeks later which stopped it until just now it did it again. The sputter isn't constant I notice it only does it when I get to about a 1/4 of a tank. And to describe the sputter it acts like it's about to run out of gas sorta. The only mods I have is the dezod header and an agency crank pulley.

 

Well it sounds like its not getting fuel or at least that's my guess. If its a 2nd gen I'd be surprised if you had enough crap in the bottom of the tank to clog the in tank filter/screen. Gotten any cel's? Maybe buy a pack of sea foams and use them with every tank for a while to see if something gummed up?

 

Why would it be specific to a 2nd Gen? And I will try that

 

Just sheer mileage. Sludge or dirt in the tank usually takes quiet a while to build up from what I've been told. Enough to clog up filters

 

I JUST ROLLED OVER 20,000

 

I'd go to dealer with it but make sure to either take them for a ride to show them or tell them how to replicate it. I spent $200 in "diagnostic" fees for them to say they couldn't tell I had a bad synchro. 2 seconds with me driving the tech and I got it replaced
