So Installed the cobb stage 1 to the car and soon as I throw 3rd gear and at around 4500-5500 rpm car starts breaking up. I have only done downpipe and 3in full exhaust with flowmaster super 10 in the center. Car doesn't have an intake I Dont know if it has anything else.

COBB stage 1 requires you to have at least a drop in filter. Do you have a drop in filter?

He can get away with the stage 1 on a completely stock car if he wanted too. A air filter wouldn't cause what he is describing unless its completely clogged. Id look toward the plugs, are you still on stock spark plugs? If so you should get the one step colder plugs from tune+ make sure you're gapped to his spec. Also have you swapped out the low side fuel pressure sensor for the newer design. One symptom of them starting to go is cutting fuel at higher rpms.

Now all that being said, you should get a aftermarket drop in filter and then look to a intercooler if you want to be tuned. Your car can run the stage one stock, but you're gonna suffer from heat soak bad.

Well I just ordered my spark plugs and coils.

I wouldn't worry about the vapor hose unless you're throwing the code for it. I also wouldn't worry about the coils unless you're seeing some issues after the plugs get swapped.

When you said your car is "breaking up" I was picturing this though...

replace and gap your spark plugs correctly! And I would replace your low pressure fuel sensor.
Part number for the fuel sensor is BU5Z-9F972-B

the fuel sensor probably won’t fix the issue you are describing because I had the same issue and my low pressure fuel sensor wasn’t working at all but I replaced it because it can cause great harm if it’s not working correctly.What fixed my issue were new spark plugs that I gapped to .028

hope this helps!

Just got my car back from dealer service and my sensor was replaced for bad signal after my lost-boost event described in another thread. I'm guessing I may have had a serious detonation that sent the system to limp mode. No proof, just a theory. Funny thing is I had already replaced the original with the -B version. Another data point in the Great Fuel Sensor Debate as to whether there is a difference between the two different versions
