05 NPR II

TVA · 2020-10-28 22:08

if anyone had Isuzu NPR working OK on idle and bog down and start missing two seconds in to driving - please share you experience! No codes!!! The only thing odd is intake air pressure not changing - but that’s understandable with ECM cutting fuel. After shutdown and restart will work OK until start driving again. It is not a fuel problem! Was checking powers and grounds to ECM when Zeta decided to start REALLY blow. Also would like to know where are terminators in this thing?!

    Update. Terminators are OK. What this thing does, is it feels like it goes in to the limp mode without setting the codes as soon as you start driving. But if you do torque converter stall test, it will gain power after a few seconds into stall testing. It will drive good for a while, then gets in to limp mode again. The only thing noticeable is TPS factual position is constantly 3% different from desired and estimated. And feels like MAP sensor is not changing reading fast, but I am using CanDo, so it might just be scan tool.
