A few cyl running lean/ and hot

I have a 1994 jeep cherokee with the 4.0L. Has 180K miles on it. This winter it started to run lean. Found had 2 leaking injectors and a bad fuel pressure regulator. Replaced them plus the spark plugs. Have an over heating issue now and have a 2 row radiator that has less then 15K on it and a high flow thermostat housing. Just replaced the thermostat and 16 PSI radator cap. Still running hot. So looked at spark plugs and cylinder 1 and 6 are a bit white on the spark plugs. So thinking the lean condition is causing the running hot like at 240 degrees in idle and 210 driving. It has in last year a new MAP and 02 sensor. Any suggestions?

Run a can of BG44K through to clean the injectors, or if you can't find that, run a bottle of Chevron Techron fuel system cleaner.
