Greetings Karlos, first and foremost what engine model your trooper 93 has? If it is 6 cylinders there are two variants, one dohc and the SOHC, both are easily recognized, the first one has the admission throughout the engine front, while the Sohc has it on the one hand, these models do not use a distributor, but the module that has 3 coils, a common problem in the dohc is that it uses some chains inside the cameras, with their respective "skates" or tensioners (Sometimes it breaks), unraveling the time of the cams, eye I do not talk about the time strap, but of a chain that moves the admission and escape cam, the DOHC uses 4 cams, therefore it has 2 chains. Check that if your case and tell us. Greetings.
