75 series 1hz engine problems
i have a 98 75 series 1hz at 2200 rpm it develops a miss not there before 2200 or after and all so has a flat spot at about 2000rpm when it is cold it seems okay but at full temp it starts to play up also seems a little jerky at low speeds any imfo would be great
i would start by looking at your airfilter and intake hoses, if they are free of crap
its most probably a fueling problem, too much bypass id say, from worn seals at high pressures, get the injector pump and injectors looked at.
It could be as easy as leaky injectors or partially blocked ones, so have a tech check them b4 they open your pump.
