my service engine soon light either flashes or stays on.It is running very
shitty and sucking up the gas.There is no power going to the data link so
I am not able to retrieve the trouble codes. I have replaced the pcv
valve, cap and rotor, plugs and wires, oxygen sensor, fuel filter, changed
oil, air filter and it still runs the same. What else can I do?

The simplest thing to do is get to a decent garage. Have them hook a
scan tool to the ALDL connector and read what problems it's having. Most
decent places will only charge a diagnostic fee for this.
if you do remove it, buy yourself a piece of like 3 foot long exhaust pipe
and have someone you know weld it in place of the Catalytic converter, dont
do this if you have inspections in your state, I've heard its a MAJOR fine,
here in Indiana we dont have them so.....
This engine had two common failure items, both could cause your symptoms.
1. EGR valves plugged. Generally can be fixed by removing and cleaning out
the carbon build up
2. CPI fuel pressure regulator and/or fuel line (called nut kit) feeding the
CPI unit leaks fuels. Both are located inside the upper manifold. Fix is
to replace the CPI unit and nut kit.
