Hey guys im new and this is my first post but anyways im having issues with my G's iding. It all started when i wanted to get new spark plugs because i just purchased the vehicle and i wanted to do alil bit of maintaining but when i change the new plugs and start the car it starts to run terrible and i mean terrible and turned it off and started it again and it didnt wanna start. So i pulled the plugs and seen one of em wasnt gapped correctly at all...it was literally touching together and so i got an new one and its still idling rough but it wasnt before i changed em so i changed the valve cover because i thought that was the problem and it still didnt fix anything... idk what it can be because all of the plugs are gapped correctly and i installed an new valve cover and the ecu isnt throwin an codes but when i rev it to 2.5k rpms the check engine starts to blink so that made me think maybe the car isnt getting enough fuel and its throwin an lean code ikik i gotta see what the code is but im too scared to drive it to autozone or oreilys... i think it maybe the fuel injectors????? Any ideas ???? Helppp plzz i gotta walk to work 😞😂😂

 

If it ran correctly before the new plugs, then ran BAD immediately after the new plugs, then you probably swapped the coil pack harnesses accidentally.

 

Also, that flashing CEL is telling you what a problem is, scan it so you can listen to what it's saying.
