Losing power while going uphill

hathi123 · Oct 2, 2024

Hi my name is albert
I got a d22 yd25 and having issues with it going up hill.

I have recently changed my neutral position sensor and still doig it.
But it still feels like it misfiring in 3rd and 4th and only under load

I was wondering if any could me or tell what else I need to look at.

Thank you

Hi, I'm just wondering when the last time the fuel filter was changed?

That probably rules the filter out as the problem, but if it's dying under load, it's probably a fuel starvation issue.

Thank you i will have look in to it and i might need a scan tool so i get the ecu to relearn the new sensor

i would change the filter anyway. its cheap to do.
what sensor was changed?
afaik the only sensor that it learns is fuel pressure and throttle position. there is a procedure for resetting without the scan tool. i recommend doing that after changing fuel filters.

also you can double check the neutral position switch is working by using the idle up switch, rpm should go up in neutral and drop back down when in gear.

Yeah it was the neutral position sensor and high idle works but im only loosing power in 3rd and 4th gear still even when i changed it

with high idle on does it drop the rpm when you select 3rd or 4th ?
just because you changed it doesn't always mean its fixed. its also not a sensor, its a switch.
