Have a VZ Commodore Executive 06 Alloytec engine. Thinking the problem is auto related
When sitting on 80-90km/h and go to gradually accelerate the vehicle has no power and shudders/ jolts until you out foot down harder and it increases revs or goes back a gear.
Vehicle drives OK in third gear. More noticeable when aircon is on
Checked vehicle not misfiring under load (drive, brake on and high revs)
When disconnecting each coil the engine changes note and runs rough
Auto has always had the usual thud when going from 1st to 2nd when cold
Any suggestions or things to try. Thanks !
