Hello Everyone,
Just to mention that once I had a problem with a display light came here found the solution. So I'm back again. Air conditioning not working. I had paid someone to charge the system which they did. Worked great for a day or so. When it got hot it didn't work. I have a can of leak detector. Just had to find out which was the high and low side of the system. Couldn't tell by touch, system must be low.

Welcome to this forum! The low side is closer to the evaporator. The high side is closer to the condenser.

welcome rwhill

Just recently changed transmission; (easier for me to pull engine/trans) while I had the engine out thought I'd do the timing chains also. Everything back in; have started the car ran but to much shaking. Vacuum leak somewhere. I found that I'm not getting vacuum to egr and fprc. I also have gas coming out of my exhaust pipe

Check the vacuum line on the fuel pressure regulator. The diaphragm might have ruptured, and is leaking fuel into the intake system in the engine.

I don't have vacuum on the fuel pressure regulator or the egr valve. I guess I'm going to trace the vacuum lines. Maybe this will be a good one for smoke? It has to come out somewhere.

fprc is the "fuel pressure regulator control". It's located on the drivers side of the engine of the vechicle Just below the coil pack.
