Engine is giving off an extremely pungent fuel smell and the right exhaust pipe has white smoke as well as some coming from the engine. I just replaced the O2 sensors and now im getting codes 311 and 314(thermactor) but I don't even have a smog pump I never had this issue for a long time. The engine hydrolocked with fuel not too long ago, fixed the injector that was leaking had them all cleaned, bought a new fuel pressure regulator and adjusted it to 30psi (which I was I formed is the correct psi) and it was good for some time but now I'm running into a similar issue. There are no cats, no smog pump, new fpr, new air filter, just did an oil change, new distributor and cap, new spark plug wires and spark plugs, injectors cleaned and fixed, new fuel filter, had it tuned recently I think about ~13°, no holes or anything in under hood fuel lines or leaks. It burns through gas very quick, difficult to start and when it does it quickly stalls and cant keep steady RPMs, is there something im missing?
