Have an iveco 4cyl tector which is very slow to build up engine revs,once at 2000rpm turbo boosts and pulls o.k.No warning lights on. Have checked intercooler/piping,airfilter,fuel filters,turbo seems ok.Can anybody recommend something i may have missed
try changing map sensor on inlet manifold 2 pins fitting and one plug on it about £120 so if you no anybody else with same motor try swapping to prove fault, but more than likely it.
