Q: No Power, Bad gas smell on 1992 Lexus SC400

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Out of nowhere my car just went, bad smell in gas, hard vibrating, and wouldnt stay idle. I had to press on the gas just to get it to stay in idle. The check ingine light is on but is not getting any codes. Ive changed the driver side catalytic converter but still the same. You can smell gas really bad and I cannot accelerate over 30mph. The car still drives, but very badly. HELP!!! any ideas from anybody? MY mechanic wants me to change the whole fuel line system. And Im not even sure if thats what is wrong. Again I ask for help.

If you smell gas, then you need to find the leak, it could be just a hose fitting, not the whole system, it could be the filler neck or a worn out fuel cap.

If the Check Engine Light is on there ARE codes, you just need to find a shop that knows how to retrieve them and when to do it. I do it on this year Lexus fairly often, if in fact the Computer has failed to the point where it will/can not show codes, then the Computer it self is bad, but this is not common.
The gas smell is like a gas exause smell. I took it to the toyota dealer and they said that some kind of thing with my cat converter was not mixing it was getting to much fuel or something....they told me that it was trying to fix itself and i should not i cant even get it to the dealership....Could it be the EGR Valve? I mean it cant be the cat converter because i just changed it and its still not doing right.....anymore advice? PLEASE??
