Fuel Pressure

[craigo53]

This has probably been asked before, but I have a 96 Teg LS with a B20 swap in it, and i was wondering what fuel pressure i should be running. Its pretty much a stock engine with some bolt on's. Thanks

Stock fuel pressure, which I believe is 44-48 with the vacuum line disconnected.

didnt know you had to disconnect a vaccum line to check fuel pressure?

[craigo53]

Thanks i'll check it tonight after work. I think it's running a little high cause the guy that had it before me likes to run his cars rich. Also should i be running higher octane fuel in it?

with a b20 with nothing done to it? no i would run plain ole 87 in her.

[craigo53]

Ok well i went home to check the fuel pressure and everything checked out ok. so i don't know what else to check, but here is what the car is doing. When i accelerate from idle to about 3 grand it cuts out like its over loading or getting rich on fuel like i thought. so i don't know what to do now. where do i go from here?

That's the way it's supposed to be done. The pressure readings are different with the vacuum on and off...and the manual doesn't list a pressure with the line on.

Unless its the 99-00 higher compression B20Z, or the timing is advanced.

Does it do anything else, like idle wierd? My old prelude had the same problem, it'd bog from being overloaded until about 3500 RPM...it was just after having the motor replaced. Turns out the shop routed the vacuum hoses incorrectly. Check that...maybe it could be your TPS?

[craigo53]

Where is the tps located? and is there any schmatics anywhere that i can look at to look at my vacuum lines?

[adictionbass]

tps is located on your throttle body, opposite where your throttle cable connects. Its held on with rivets.
