Fuel or air issue?
Hey, first time poster here, just got a '92 GL on Sunday that needs some TLC but I'm really excited for it!
I'm a bit of a noob with cars in general but know a thing or two. A lot of the reason I bought my Festy is to learn how they work/how to work on them and slowly restore it over time.
With that being said, i bought it from a guy who was transparent about a fuel issue that it's having. It runs and drives but pretty rough, and going up even a low grade hill will cause it to sputter like crazy and it was topping out at about 20mph. Was barely able to get it home.
Seller said he put in a new fuel pump (yet to verify for myself but don't see why he'd lie about that) as well as a fuel pressure gauge against the fire wall. When it was idling warm it was getting 20-25psi which according to my research is low but it stayed idling, just rough. Today I started it up cold and was hanging around 30 but then died. So it runs/idles while warm but stalls out when cold. Also noticed when pulling away from a stop it really threatens to stall until I get the RPMs up a bit, but with lots of sputtering.
He also said it had been sitting for about three years so maybe bad gas could contribute?
Also, temp gauge only ever got barely above the bottom notch. Seller claimed the gauge works when I asked.
From what I understand this points to a fuel issue like the seller said also feel like it could be a vacuum issue as well. Open to any ideas, really. If someone could point me in the right direction or a few things to try that would be great. Definitely not looking for the absolute solution as I know this will take some trial and error but just wanting to know where to start.
This ended up being long so thanks for reading!
