Fuel pressure is 60 psi.

 

By the readings, I assume that the catalytic converter is plugged or restricted.

 

Pulled #1 catalytic converter, the insides were all busted up. Dumped it all out. If I put it back on and try to run the car, will it cause additional damage?
Can't go right put and buy a new one.
should I buy just one or see about getting all 3......

 

Put empty converter back on, no changes....
all readings are the same..... look at previous comments....
fixing to call it quits.......

 

You may want to inspect the other converters for damage if you have one damaged.

 

Just curious, if the others are bad, wouldn't I get a negative reading on shtfl2 also, not just on shtft1?
