I don't have a AXIS. I was at TIMM's a few weeks ago and was watching his thread to see how it was going. You guys are in a skill set way past me.
In late on this...New fuel filter, 43 lbs w/vac off, 38 w/vac on. Never changes with winging or running RPMs up.
this will decrease fuel pressure as vacuum increases causing a lean condition.Just so you know, revving the throttle will not increase fuel pressure. The engine has to be in boost to put pressure to the fuel pressure regulator to increase the fuel pressure. In park, you can't make boost.
Hi timI believe that I have ruled out a vacuum leak, as that would affect the idle more than off idle and higher (midrange) RPM.
Why not go to bigger injectors rather than higher fuel pressure?
Or just add fuel pressure temporarily, just as a check?
Is my combo out of the ballpark for 60# injectors? I seem to be out of fuel without even getting the RPMs up, let alone loading the motor....
Thanks for the help so far!
Three yrs is a long time sitting and fuel does evaporate leaving behind its remnants. I think I'd be pulling the injectors out and running some thing through em with a nine volt battery to cycle em at the least.only have less than 10 miles on them, and ran fine when I started this project before the new motor THREE years ago last January. That also doesn't mean that garbage hasn't clogged an injector with crap from between the new fuel filter and one or more of them. Even tho everything was cleaned and flushed thoroughly from the tank foward before the filter was replaced.
