Missfire

[Kev58980]

V6 ecotec, auto, 350000km, engine misfire on exceleration from idle to about 2000rpm, engine feels like it is going to stall and the accelerator has to be pushed firmly. Then excelerates fine. No noticeable misfire at speed.

When mine did it was the fuel reg had blown from a big pump install.

Does it smell fuely? How did the plugs read?

No fuel smell. I'm an old time diesel mechanic and not sure what open and closed loop is that people talk about.
I've ordered a new coil pack. Hopefully that will fix it. Hasn't missed a beat over the years.
Covid has killed my bank account for car repairs.
