'95 Jimmy 4x4 Bad Acceleration
#23
Transmission must've been over filled. Dropped the pan then added 5 quarts and 24 oz of Lucas transmission fix. Acceleration is almost perfect, so I'm headed to check fuel pressure now. Then tighten those exhaust lines down. I also noticed the oil is a little over filled so I'm going to drain some out and see what that does. In case I change the oil, how many quarts at refill?

Did you fix the twisted fuel line at the filter? If so you may have a bad fuel regulator. When you said motor oil was overfull does it happen to have a fuel smell? If the regulator is leaking externally it will go in the oil.
#27
No I haven't had the money for those pieces to build another line. I can see if I smell gas in the oil when I go to drain some in a second. Would the twisted line cause the rapid leak down on the gauge? And could that regulator leak cause my lack of acceleration?
#28
I assume the fuel filter is in working condition too.

The twisted line could cause the lack of acceleration and the regulator leak could cause the rapid leak down on the gauge. Your video shows an immediate jump to 60 psi. That's good pressure. Then it drops immediately. That's a failed leak down.
The next step is to test the fuel pressure and leak down at the filter. It should reach 70-100 psi and remain above 50 psi for 10 minutes. If the pressure holds above 50 psi at the filter, then the leak is in the intake. If not, the leak is in the tank.

Ok I'll do the test at the filter. What about the possibllity of bad o2 sensor? This guy has the same symtoms as mine...
