Truck was missing horribly when I got it, the guy before me said that it was running great, then he pressure washed under the hood. so I took it to the mechanic for a tune up. mechanic said that a tune up would do nothing, low compression in numerous cylinders. when I drove it home from the mechanics it ran perfect, no miss or anything. then it started when the truck warmed up. so I changed the plugs thinking if it was a major motor problem it would not just come in and out of runninf great to horrible.. it ran awesome again, until it warmed up. advice?
