I recentley purchased a 94 camaro z28. I noticed a strong gas smell when driving it and long afer parking it. It also idled kind of weird. When I decelerate the rpms drop to about 550 but then goes to 1000 on its own. Sometimes when the rpms drop it is not able to recover and stalls.

Check the fuel pressure with a fuel pressure gauge designed for your fuel system and comeback with the readings we start here.

Check the idle air control valve, throttle position/ mass airflow/map sensors to include the CPS.

I found the problem, there was a cracked hose on the charcoal canister and this was what was causing the smell and bad performance. Just thought Id let others know in case they have the same problem
