I have a 1991 auto VN and when i put it into reverse or drive (any gear) and put my foot on the accelerator it drops revs to almost stalling. It doesnt do this in park or neutral. I have had the IOC valve and throttle body cleaned out. Anyone got any ideas of what could be wrong??
Didn't check the codes and have already started to pull apart throttle body, manifold, injectors etc to see if they are blocked or damaged. just had it serviced (twice) which has made it worse!!
Had similar problem was a burnt valve or valve not seating properly. Take all plugs out, put one back and turn motor by hand you should feel the compression, move plug to next cylinder , do same agian, this will either confirm or elimibate a compression problem
