My engine was overhauled lately due to oil pump malfunctioned and it has a knocking sound when I got to Motoshop, luckily no grave damage from the pistons and others, but it is overhauled and it went well. When the job was done, the Mechanic test it for about 10 or more hours before releasing it to me. My question is it ok, that the idle is rough especially when the AC is on, it fluctuate from 750 rpm down to 500rpm in a split second and back to 750rpm, sometimes when the car is in traffic, AC blow is like newly open, what could be the cause of these or is it normal since it is newly overhauled, I got it out from mechanic as of this writing is 2 days ago. Any enlightenment would be great nd helpful. Thanks in advance, BTW, My car is Hyundai accent 2011.
Nissan is bringing in the Primera nameplate back. I hope it's not going to be some boring crossover but a car that will have superb handling, good responsive reliable motor like the Primeras of pre 2000. I also do hope they don't go under and the Primera becomes their saviour.
