So i have an issue. I dont have any engine codes so dont really know where to start. The engine has started missing really bad. just dead miss. no power. Just need a place to start. i recently replaced the fuel pump that fixed that issue. but now i have this issue.

If this is the multi port injection engine, remove the circular peice on top of the motor when the vehicle is not running, two torx srews, take a flashlight and see if you can see puddles of fuel in intake system, mine just did this to me, turned out to be fuel injectors,(spider system) mine was only using driver side cylinders at the end, if there is fuel in the intake, go to rockauto and get the reman injectors. gb manufacturing.
