Just got a CEL!!!

[babamerino]

So I installed my Longtubes and got a re-tune on Friday… Everything was awesome!!! But tonight I noticed a rough idle and when I let off the brakes to go it kinda stumbles on and when I accelerate its like its not all there… Its not accelerating like how its supposed to be, almost like thereʻs too much air. Gonna email Justin but just thought I would get some other ideas… Thanks!!!

Just wait for Justin, you don't need to running down wild goose chases.

Okay this may sound stupid but. Check your air intake at the throttle body.
Just simply pop the hood and look. If you have aftermarket which I'm pretty sure you do if you have LTs then it could of come undone and that would mean you have entirely too much air. Happens to me all the time. Same symptoms.

Could also be something related to the oxygen sensors.

Per my mechanic friend... He said to check all the spark plug connectors and sure enough, the very back left one was loose!!! Plugged it back in and now she runs fine!!! But two concerns... 1. He told me to do a O2 sensor test prior to the plug test and the mass made the is drop (which is good right?) but the two under the car didn't... Is this a concern? 2. The CEL is still on. Any thoughts? He said to definitely change out the spark plugs and maybe the bottom two sensors... Thanks!!!

The lower 2 o2 sensors are set to not report(turned off). I don't know of any tuner who would leave them active with longtubes on the truck.
