I cannot figure out what is wrong with my car, I pulled off my o2 sensor yesterday and when I put it back in the car will not stay started because it runs so rich. The thing it bogging and chugging till it dies and while this is happening it turns on a check engine light but as soon as it dies the light goes away (the exhaust smells like gasoline). I unplugged the O2 sensor to see if it had something to do with that but it had no affect on it.
I dont know if its a main relay or what the heck it could be because I really didnt touch anything else since i ran it last.

...now another thing that im wondering about is that yesterday I installed an apexi that I have from a trade laying around to check it out but i have made 0 adjusments to anything and it even ran with it installed yesterday before all of this...I honestly am not sure what it is of anyones got an idea i would appreciate it!

plz help me I cant figure this out and im about to pull and resolder the main relay to see if that has any affect...I hope someone can help me by the time i get back

 

O2 sensor won't cause symptoms that extreme. Leave the main relay alone. You installed an "Apexi" system and then the problems started after one day? I would double check anything you messed with for poor or incorrect connections. Or better yet, remove the system and start over once you get the car running right again.
