Cel help?!

[AnthonyCeli]

Hi guys, I have a 2000 celica gt automatic. My CEL came on a few months ago pulling a misfire code, cleared it was good for about another month then it wouldn't go away. It is still on and the car is running awful, boggy starts, idle is rough, acceleration is bad, and burning through gas. I recently changed front o2s, coil packs, spark plugs, cleaned MAF, and checked the injectors. None of it fixed the problem I still have Multiple random misfire, misfire cylinder 2 & 3, and lean code. Had anyone had this problem any feed back would be helpful thanks! Oh also it says my EVAP is inc.

Are you running the right plugs? Also try cleaning out your throttle body with some cleaner, sea foaming the car also wouldn't be a bad idea, I did it to my car when I had a rough idle and it solved the problem right away. Anyways best of luck with your car man.

I was running OEM plugs from the Toyota dealership but then got cheap ones just to see if that would clear the codes. And I cleaned the throttle body as well. My next idea is smoking it to see if there are any vaccum leaks. And yeah I want to seafoam but I'm kinda nervous haha.
