Hi If it were me I would check all my wires to make sure one is not broken as well as intake and exhaust leaks. I had a big problem like this and the wire
from the temp sensor to the brain was broken internally. man did I feel like a dumby after I had replaced most of the part on the crazy ass thing.
Oh well live and learn.
Good luck. Jonce
