I have a 98 chevy tahoe 4WD 5.7 liter engine. My trouble is a couple of weeks ago my tahoe started to idle rough then bogg down and stall, it also began to overheat.I had figured it might be my fuel filter so I changes it. The problem continued so I got the code checked and it said my problem was my coolant temperture sensor. I talked to a few people who usually help me with matinence on my tahoe and they said to try cleaning the throttle body, change out the coolant temperture sensor, thermostat, and the idle air control vavle. I have change and cleaned it all but the problem still persists. I am hoping that it isnt my fuel pump. Do you have any ideas on what I might need to do?
ive also noticed a coolant leak by the throttle body but I cant see where exactly its coming from
