I recently had my engine replaced bc of bad compression after going turbo. Sold the turbo and got a USED 110K mile motor. Drove it 900miles and went WOT one night and the car starts popping from the exhaust. Didn't think anything of it till the next day I went WOT again and got to my destination and turned the car off for a good 1 or 2 hours. Turned the car on and it struggled. I thought it was weird so I turned it off and then back on and it struggles but this time with the 2 codes.
took it back to the shop and the shop warrantied my engine and got me another engine at 55k miles. compressions on this engine were really good. BUT the problem still exist!
I can't think its an engine problem. The only thing that was pulled out and replaced was the engine so what gives?!
Is it an ECU issue? Harness issue? PLEASE HELP ME GUYS!!!
