Zulfiqar bhai salam. Hope you are doing well. I'm sorry but I'm bot getting this comment. If you can please simply explain it in simple language as it's technically difficult for me to understand. 🥺 I recently got my xli 2009 complete overhauled including rings pistons bore etc. Engine sound is ok. I haven't speed it up above 60km/h with rpm always below than 2.5. For first 100 kms i drove it till 40 50. Now i take it upto 60 max with a light foot. Kindly guide if its right way. A day back i had to speed her up on a busy U turn and got the car upto 3.5 4 rpm but felt it hard to pick up like missing type or timing issue. On 3rd 4th gear car acceleration is good and goes easily to 60 70. Kindly guide if this pick issue on 1st gear on high rpms will settle down.
