...It still died.
...I have noticed a couple of changes today. First, the LT Fuel Trim is at 148 and doesn't change now. The ST Fuel Trim is at 128 and has quit changing. The O2 sensor seems lower now with the readings staying below 200 mv.
There are also two other things that bother me. First. When I try to run it at WOT, it will surge and not seem to get to full throttle. I don't see any fluctuation in the TPS voltage. Also tonight it started surging while at idle. This seemed to start happening about the time the LT and ST Fuel Trim went high.
I assume you have a mistype there. Here are the fuel pressure specs for '95 (from TECHINFO):
1995 L-1: 41-47
1995 K: 48-55
So, is it fair to assume you are reporting 42 psi?
If so, it'* important for us to know what your trim level is. Is your car supercharged or NA? There is a difference in the expected correct fuel pressure.
You say your fuel pump is noisy. That is usually a warning sign.
