So here's the issue. At intermittent points during driving whether under WOT or not, the car seems to hesitate or have basically no torque, then randomly kicks back in 1sec later. No misfiring, no noises, no smoke, no CEL, no nothing, just the loss of power. It is most notable when taking off from a stop but there's no way of predicting when it happens. It happens through the entire rpm range and there is no rhyme or rhythm to it.
I have also only noticed it lately (within the last few weeks), when I swapped back to the Proton ECU and injectors.
So what are your thoughts? I assume if it was injectors it would be constant not intermittent. Could it be ECU related? O2 sensor? Old dying engine? (260k kms). Just need some advice on what and how I can check so I can eliminate potential sources of the problem.
Thanks guise.
