My check engine comes on when in driving if i take my foot off the gas pedial and that apply acceleration again the light gose off. when the light goes on i lose power

I also have experienced this problem with my Isuzu D-Max pickup. Did the problem occur when you were having a long drive? Coz it happened to me when i was already driving for 1 hour at a regular fast speed. After that, the problem stilled continued, especially when i reach 100km per hour.

What I did to fix the problem was i had the pickup's alarms calibrated by an Isuzu authentic service center. Coz only Isuzu service centers can calibrate the alarms and i think they're the only ones who can diagnose the car's problem if the check engine alarm turns on.

After that, we found out that there was no problem with the engine. Just the "check engine" alarm's calibration.
