Intermittent starting issue

I have a weird issue when I start my truck for a brief moment than start it a few hours later it seems rich . I replaced plugs (ngk platinum) ,cap,rotor,fuel filter and cts . This is a 1997 tacoma 2.4 with 225k miles

 

Leaking injectors ??

Just why do you think it is over fueled ??

 

It seems when I give it gas it seems too clear .The cat and o2 sensors were changed for a P0420 .I just cleaned the maf along with unplugging the battery

 

Just how air you giving it gas ??

The only fuel comes from the injectors steeping on the throttle only opens the throttle body allowing more air

 

pressing the gas pedal

 

Do you have mass air sensor on it??? I'm not familiar with 97's. They can make it hard to start or run smooth. Check all you hoses and nuts or bolts to make sure you don't have a vacuum leak.

 

update after starting it and letting it sit for about 6 hours it did start and run smothly after cleaning the maf well see what happens .
