Hello, i recently bought a 92 sooby loyale, it was running bad and missing horribly, water pump leaking, clunking when accelerating, engine ticking, the people that sold it to me said a mechanic wanted to charge them 800 dollars to fix it and had to pull the motor... I found out that it was just a bad spark plug wire.. changed the plug wires, fixed the water pump, changed timing belts, and put in a new mickey mouse gasket in the oil pump... it runs pretty good now ! Have you checked the plug wires ? sometimes you can use an ohm meter to check them. I got a new set of plug wires for 8 dollars...
