Look like the design change was later, but 1998 might be iffy unless your 1998 was made in 1997.

Isuzu North America also offered a three-door version under the name Isuzu Amigo, sold as the Isuzu MU in Japan. A second generation of the SUV was released in 1998 for the 1998 model year, with the three-door Amigo becoming the "Rodeo Sport" in 2000 for the 2001 model year.

We do not have these diagrams.

If you have oil in the anti-freeze it is most likely the head gasket or the head itself that has cracked or warped allowing oil to enter the coolant passages in the head.

Probably you mean a throttle position sensor commonly referred to as a TPS. They frequently go bad. Google "Isuzu TPS" for location diagrams and other info. Once installed, there are likely to be adjustments needed that require equipment. Any Isuzu dealer should have one in stock.

Maybe intake gaskets leaking.
