3 cel codes

My car has these three codes that keep popping up: too rich, too lean, and random misfire. I noticed when I installed the ttr solid engine mount it was idling weird and the throttle had a hesitation at around 2 or 3k rpms. In order to install the mount I had to reroute the sri towards the drivers side (the intake pipe is tight and the maf is plugged in...). Since then I have changed the spark plugs and serpentine belt. My next plan of action is to change the fuel filter and clean the injectors and tb. The throttle doesn't always have the lag, mostly when I floor it. What else should I check before I take it to a shop?

First clean your tb, and put sea foam into your next full tank and run the whole tank thru. If its still having issues, you should look into your front 02 sensor, as that is the one that controls your are's unless you are wot.

All three of those symptoms point to 02 sensor, but a dirty injector will do this as well and a dirty tb will make it seem sluggish on throttle response.

I think your intake is leaking and therefore your "MAF" is not reading proper airflow.

Do you mean he might not have installed the right ones or not gaped right?

I put a can of sea foam into the gas minus about an oz I put into the oil.
Took the tb off
Cleaned it
Checked for air leaks around the sri and decided to make a gasket out of electric tape to go on the tb where the elbow clamps on, it was the only place that could possibly have a leak.
Thanks for the fast responses and I will give an update as soon as the gas runs low.

Probably your makeshift gasket on the TB making things worse.

---------- Post added at 02:38 PM ---------- Previous post was at 02:37 PM ----------

Also, from your picture your intake isn't far enough down the lip of the TB either.

Last post before you answer!!! What did you use to clean the TB?
