Zac Posted April 26, 2006 Report Share Posted April 26, 2006 About a week ago I pumped gas w/o turning my engine off. Ever since when I'm crusing or at idle, it'll intermittently start to die or lose all power for a second or two (but never actually fully die.) The AFRs will go up into the 17s-18s, forcing me to either downshift and floor it (the AFRs do go back to normal when at WOT) or put it in neutral and wait for it to get a bit better.I figure that pumping gas with the engine on stired up some crap at the bottom and clogged my fuel filter or messed up the pump. Are there any tests I can do to eliminate non-problem parts? (IE: fuel pump isn't cheap and I'd probably be stuck with OEM from the dealer as I'd only have tomorrow to work on it so any way to find out if it's a different problem?)(by the way: it's a 96 850R 5spd) Link to comment Share on other sites More sharing options...

Zac Posted April 26, 2006 Author Report Share Posted April 26, 2006 exactly - like I said I've never played with the fuel stuff on this car. Other fuel pump I've had out before had a little mesh/screen thing over the inlet to the pump. Is this the filter or is there also an inline filter on the 850s?

JMK33 Posted April 26, 2006 Report Share Posted April 26, 2006 I think they are talking about an inline filter, the mesh screen wouldnt filter the gas going into the engine. Link to comment Share on other sites More sharing options...
javadoc Posted April 26, 2006 Report Share Posted April 26, 2006 I'm a bit concerned that you've aparently got a wideband and don't know where the fuel filter is... Link to comment Share on other sites More sharing options...

It is relatively easy to do and it could be your whole problem. Link to comment Share on other sites More sharing options...
