wont start the car on jack stands

:bump::bump:, its throwing code 43 now im going to try basic fuel diagnose cause i dont know much about it but im going to take a look at injectors, fuel filter, fuel pump and how do i check if fuel regulator is working properly?

i had ALOT of lists on my “to do list” so yesterday got my intake manifold cleaned out it was black from getting dirty without intake duct or filter and bought manifold and throttle body gaskets and cold air intake bolted it up runs better i hope bogging is gone its not throwing any codes any more i might want to put new o ring and kit for injectors cuz filter thingy on injectors are dirty might as well causing code 43 pop up

try disconnecting the o2 sensor. see if the bogging stops

it was 02 sensor wire cause i forgot to tie them up it got melted on the exhaust dammit

i cleaned the iacv and fitv few months ago cause it was idling too low and cleaned the intake manifold last week cause it was dirty so i cleaned it put it back together with new im and tb gaskets, didnt have problem til now it likes to idle at 2,500 at cold start in the morning only about 70 degrees outside not 20 degrees lol i think it might be idle adjusted too high or fitv not screwed in enough
injector kit will be here sometime this week it includes 4 basket filter o rings and upper grommets and lower seals from ebay cause my basket filter some of them are clogged im going to try to figure how to test and clean the injectors diy on youtube lol
