I went to computer tune & lube to get my O2 señora replaced on my truck 2 weeks ago. I left there and noticed the engine light was still on when I had just got home. My neighbor had noticed that some wires were unplugged underneath my truck. He connected what turned out to be the O2 sensors and the engine light went out. They had also replaced the water pump and told me there was an issue with the oil pan which had to be replaced. He stopped working on the oil pan, flushed the radiator, and mixed in liquid gasket sealer. He then told me the head gasket needed to be replaced and it would cost me $1,800.00! I took my truck to another mechanic and he checked it out for a few days and said 2 hoses needed to be repaced, and NOT the head gasket! these guys are very shady and would manipulate, lie, cheat and steal to make money. And the Manager appears to be a wicked drunk!
