Working on the 4runner

The 4runner had problems on our trip to Vegas ( made 100 miles). We took it in to the dealer in San Bernardino. ( who couldn't figure it out) so we delayed our trip to Vegas, drove home switched vehicles. After Vegas, we took the car to a local mechanic who said he switched injectors on #4 ( turns out he did it on the wrong cylinder). He recommended we take it to another dealer who said " your #4 injector is bad". The cost would be $300 for parts, and $500 for labor. I decided to fix it myself with some advice froma friend. I bought the parts for $150, took apart the fuel and air intake, took off the intake manifold (shown), lifted the fuel rail, and swapped injectors. Reassembled in reverse order, and now it runs great. it took me 2 hours of my time. saved ..... $650.....
It is good to have tools, friends, and some working knowledge of how things work under the hood.
