2013 Cruze for sale

Hello, The car had a right-side collision and I fixed it. I replaced the passenger door, fender, hood, and quarter panel. Now there's an issue: when I start the car, the pressure stays constant at 1.5, and the car doesn't perform well. Some people said the problem is with the transmission or computer, but only God knows; the engine is fine. The brakes are new, I installed previous owner's brake system, but haven't used it yet. The interior of the car is completely disassembled by me. The registration expired one Arab month ago, but the inspection is still valid. Selling as is. Mileage: 137,000 Offer accepted at 5, and I'm not far, very close. God grants success.
