Hello all, hope you are doing well. I have recently purchased off a family member a 03 KDJ120, D4D engine. It has worked perfect for a few months, but recently I've been having some trouble with it.
It seems to be an intermittent issue. Sometimes, when accelerating, specially if going up a hill, it will lose power. No matter how hard you press the accelerator pedal, it will not respond. It does not lose all power, however it's like stuck at a power level (which, if on a hill, will make it slowly decelerate), losing power gradually. This will typically last for a few seconds, and then all of a sudden it will regain power as normal. Sometimes, while it's at that state of 'power loss', it will surge for half a second. It's like it's trying to get back power. It will do this sometimes a couple times, until finally it kicks off and regains power. Has happened in different gears. Only recently engine light turned on.
Recently got a VCI and installed Techstream, was able to get into the car and also read codes. It had 31 (air flow meter circuit), 24 (intake air temperature circuit) and 78 (fuel pump system malfunction - short). I am unfortunately not sure if these codes are all new. Today I erased all codes and will be on the lookout for new codes. I also recently cleaned the MAF, after this happened.
I have attached the codes, and a few freeze frames that the system had saved. I am new to this car so I don't have much technical knowledge, perhaps I should take it to the shop, but wanted to ask here previously in case someone could point in the right direction.
Thank you!
