Hey Guys,
I'm relatively new here and to the Fox-body scene.. I had the chance to scoop up a really nice 92 that had been 351w Swapped (Still has EFI). Since acquiring the car I'm noticing a few things that aren't right. The first and right now - most important - the Fuel Pressure and subsequent issues b/c of it. Let me explain..
The car has a no-name ADJ FPR on it with a built in gauge. The gauge reads 90-95PSI !!!. There is also a HEAVY gas odor in the Oil. I suspect the absurd pressure is washing fuel down the cylinder walls and thus creating the gassy oil. Here are some of the things I've "tried"..
- Checked vacuum - There appears to be vacuum at the FPR as when the line is removed the FPR's gauge moves (increases pressure) about 4lbs.
- Manually sucked on the vacuum hose to pull up the diaphragm in the FPR - the gauge again moves - albeit ever so slightly - 4lbs ish..It appers to still be air-tight
-Turned "out" the screw to lower the pressure - best i could get it to was about 75lbs before the screw fell out- At that point the car would barely idle.
-Tried a base idle reset (youtube video) at 75lbs and wasnt able to stabilize the idle at all..
-Reverted back to 90+/-lbs and was able to get the idle back under control but at the cost of increasing the Fuel Pressure again..
What i plan to do next:
-Test the Shrader valve with another Gauge (tomorrow)- Im expecting no changes here given the gassy Oil issue..
-Disconnect the Return line and see if the pressure releases (indicating a potential clog back to the tank)..Kind of hoping this isnt the issue..
-Replace the ADJ FPR w/ a stock one.. Easiest and cheapest fix..
What do you guys think? Am i missing anything, anyone have a similar experience?
Lastly -- Im in Pittsburgh- just north of it but that doesn't matter.. what i am looking for is anyone (Shops, people, cats, dogs...etc) who are well versed in these cars and their nuances .. That i could potentially go to in these types of scenarios.. Any leads whatsoever based on my location would be EXTREMELY helpful.
Thanks!
Paul
