Salam everyone
I was planning to buy civic X after selling my white grande 16, so I went to this showroom and we agreed on a deal that we could swap cars with me giving some money on my grande, after all the paperwork I got the car out, it was a 16 model white colour turbo with 73k on odo, I felt like there wasn’t enough power and grande in this state could have smoked that civic out fyi grande was 63k driven, anyways took the car to total f6 got some HOBC in it and then took it to margalla road for some checking to my surprise I pushed the pedal the car took quite sometime to reach 140 whereas if it was grande it would have crossed 160 easily i usually do it there when it’s empty, anyway the excitement got over me and I thought it would be some tuning minor issue, but wait as soon as it reached 140 there’s a slight jerk and the check engine comes on, after that the car wont cross 120 and 4 rpm like if you push it starts jerking, I took the car straight to honda avenue and person there asks me about it and I said idk because i bought it today, and he said to me to return the car if possible because he said there can be any issue, anyways I returned the car and got my money and grande back, but I wanted to ask you guys about what could be the issue and should i go for the car as the option of that car is still available?
