cylinders two, four and eight do not work, I changed the 8 spark plugs, I tested the coils, I changed the injector connectors, I tested the injectors and nothing solved, I'm going to test the compression on the cylinders. furthermore my WJ has the following defects.

1) on motor brake it dies.
2) the auto diagnose acknowledges error P0108, I already changed the MAP and it did not solve
3) above 3500 rpm the motor fails too much.

my WJ was very much in the possession of the former owner, I'm recovering it all, it was armored, I bought a scrap to change the 5 doors and remove the armor, and I'm setting everything up before actually turning, I've been with her 2 years.

I live in Brazil, in the city of Fortaleza in the state of Ceará, sorry for my English, using google translator all the time.
