Hello. New to this forum. I am currently running a 1999 5.3 fuel injected engine in my demo derby car. Stand alone harness . My question is when it reaches a certain threshold of temp it starts to .... chug... so to speak. I have been trying zero all tables looking at coolant temp but 2 races in a row it started to go into protection mode. I know I shouldn't want this to not happen but I do. I want to be able to melt it down if needed. Please do not tell me not to. No replies would be better then negative ones. Any suggestions would be helpful. During this events I have not experienced any knock to speak of. Just no throttle and power. I am running a cable throttle.i am to the point I may just find the proper resistor and install into the temp sending pigtail to trick it into thinking its 200 at all times... help
