HH 110 and HH 262 are two Herbig-Haro jets with rather peculiar, chaotic morphology. In the two cases, no source suitable to power the jet has been detected along the outflow, at optical or radio wavelengths. Both, previous data and theoretical models, suggest that these objects are tracing an early stage of an HH jet/dense cloud interaction. We present the first results of the integral field spectroscopy observations made with the PMAS spectrophotometer (with the PPAK configuration) of these two turbulent jets. New data of the kinematics in several characteristic HH emission lines are shown. In addition, line-ratio maps have been made, suitable to explore the spatial excitation an density conditions of the jets as a function of their kinematics.
