i took it to advanced to read the code an it couldnt read any it said error but my check engine light was on before it started acting up. im thinking its the fuel injector wires. cuz the guy did a horrible job and when i tapped them down it stoped actin up just when i go over a really hard bump. its a bumpy ride cuz its got coilovers an every small bump the whole car feels like it just took off the ground.
