loosing power

    1994 Diesel hilux 4x4 struggling up freeway.

    Hey guys just bought a 1994 HILUX 4x4 Diesel single cab with a timber tray which has only done 177000kms. Frothing. But I'd drive well everywhere except driving it up a small incline but 80kms free way its stuggles. I put it in 3rd gear and reaches 40-50kms but it has these weird power drops...
