Just stopped by because I saw that they worked on Nissans and mine was running a little rough. Thought it need a tune up. After they inspected they found it to be a loose vacuum hose. Maybe not put back after I had it serviced by speedy lube. Jack refused any payments as he said they just put the hose back. Tried to treat them lunch but he refused that too. Said if I wanted to I could treat his tech lunch. I was more than happy to do that. As honest as they get reminds me of kauai 20 years ago. Thanks jack!
