So I have a 2001 Toyota Camry with 170,000 miles and I have a neighbor who owns a shop he's about 60 years old and he's always complaining how bad the economy is and how he's never going to be able to squeak by that should have been my first warning. He helped me with some spark plug wires a couple weeks ago but I told him I've been having problems with the idle and stalling and herky jerky revving ...he said you have to get an new idle air control valve. He showed me a couple of ones on his computer but he wasn't too specific about which one to get he just said you got to get one. 

So I grab it aftermarket one from partsgeek and I bring it in and he says he'll put it in for $80. I also brought him some fresh oil so I could get an oil change while I was there. 

So I hand him the part and then he has this real slow reaction where he goes oh.. is this aftermarket? 

He says let's give it a try but it might not work... Well darn it wouldn't you know it an hour later he says it didn't work and look it's making smoke now this was clearly the smell of electrical smoke I don't know why he would turn it off and then put it back on after it was clearly causing damage but I guess he wanted to show me that there was a problem. So he melted out the electrical connection and the plug and said those darn Chinese much must have made the part backwards and wired it backwards. Now he says I should go to the dealership and get the authentic Toyota version and he'll give me such a great deal on installing it so.. is this the whole short money long money deal? By the way he didn't charge me anything for this disaster... And he also had his guys wire up some alternative version because the plug was too melted so they had to grab another plug from something else and then make the wires all work..
