I have a Nissan xtrail 2001 TF30 I have replaced injectors but I am getting a white thick emissions from the tail pipe I asked a local mechanic he seems to think tooo much fuel is going in I’m pulling my hair out finding info
Does it matter in what order these fuel injectors are placed ? because I have miss-placed mine,should I put them back as they were ? I don't notice any change,I have Toyota Prius 2019,I was checking them,so I've got 3 of them with plastic on the end and the last one had none.It is straight gasoline injection.So except the plastic on the end of them,they look like new. Although I already have 100 k miles.No smell of gasoline,nothing leaking.No miss shots,No delays,it drives as it was before swap.
Fuel Injectors on modern cars are computer program regulated and they are precisely timed. So, yes, it usually matters that they are in order. Hope that helps.
I believe the o rings on mine are going bad, 13 Rogue with 296k. On occasion it will sputter and jerk and then I can smell a light fuel smell. My fuel economy will drop until I pull over and let idle briefly. It only happens at 70 mph when the pressure is higher on the seals I think. Ideas?
Honestly sounds like unburned fuel due to spark plugs not igniting. Have you replaced the spark plugs lately? I would try and replace the spark plugs, with 296K miles I am positive they need to be replaced if they have not been replaced in the last 80-100K miles. It is also a cheaper fix too. You might also consider pouring 1 can of SeaFoam in the gas tank to clean things up. Hope this helps, good luck!
@@fixit3879 yes, I have replaced the plugs with oe plugs probably within 75k, but I will check them. I already bought the injectors so I will replace them anyhow. I get codes p0137, p0138, p0139 and p0171 in random orders. Thank you for the reply and suggestion.
My car does this (please check this video watch?v=uau_BZKJ_e8) everytime I cold start it. I have asked many mechanics without having managed to fix issue. Could that be due to bad/clogged fuel injector (assuming that fuel pump and high pressure fuel pump are ok)? Or maybe something else?
90% of fuel "treatments" are either kerosene or diesel.. I've been using diesel as a fuel cleaner in a gas vehicle (carb or injected crap) for over 50 years without any type of problem.
