You have a bad EGR flow sensor. Your second post makes little sense. What do you mean by "it heats up slowly"?

code 327

i guess what im asking is would this problem or code cause overheating.
i put it on the road first time with 4.0 motor and its running hot about 220 f
when i got home about ten miles. ive done a pressure test looking for blown or cracked heads no leaks so what next to check.
