Cleaner fuel injectors = lower fuel economy...?
I recently bought my '91 4Runner with a 22RE. In an effort to gain a few MPG, I cleaned the fuel injectors, and ran seafoam through some of the vacuum hoses. Following the seafoam, my economy went up to about 18 MPG, then I developed a leak from one of the o-rings around the injectors, which brought me down to 16 MPG. I re-replaced the o-rings on the fuel injectors, and now I'm down to about 10-12 MPG. Does anyone have any ideas on where I could've gone wrong with my reassembly to cause this?
Also, I have issues starting, but only from about 1-4 hours after I turn it off. If I go to turn it on within the hour of turning it off, it spins right up, or if it's been >~4 hrs then it will also start right up, but in that little time frame, it won't start up unless I force feed it some fuel. Any help is much appreciated. Thank you!

It's recommended that you change your plugs after using Seafoam as it can gum them up from burning up all that carbon residue, as your starting issue...no idea lol
