Car stalling / bogging really bad on start ups???? If you don't get the AIR and EGR deleted with the LS1 Edit or what ever program you use...will your car begin to bog? My car drove fine with the CEL on up until I parked it last night and when I started it this morning the CEL is off and the car stalls or is just really boggy? Any idea of what this could be? I put the headers on last weekend and took out all the AIR and EGR plumbing then as well?
Any ideas would be great!
Thanks,
Ryan

Well, the car is doing it again... :thumbdown: I can't think of what it is. Possibly a bad 02 sensor itself? I crawled under the car today and the wire looks fine on all the 02 wirings.
Any other ideas of what it might be?
What does the car do when the spark plugs are bad or even the spark plug wires???
Here is what the car is doing...
Start up it shoots to 2.5k and slowly lowers then drops to about 500k where it sputters to stay alive. When I give it gas to go it is very hesitant and boggy. The car chops when it goes but once its in the upper rpms I don't notice anything. The exhaust tone itself is very strange. Not smooth and deep like normal but very rapsy and gurgly (like its choking on fuel).
I can't think of anything? I'm taking it to autozone tomorrow to have the diagnostics checked.
I hope its nothing major...maybe just bad 02 sensors or plugs/wires (wich are brand new, went on with headers).
Thanks for all the help guys.

I took the car to autozone yesterday and it threw 4 codes...
P0121 - TPS/Pedal Position
P0154 - O2 Sensor
P0300 - Random/Mutiple Cylinder Misfire
P0412 - Secondary Air Injection System
I have no idea what would cause these codes. I tried replacing the TPS in the parking lot and it didn't fix the problem. Hopefully it may be just a blown Engine Sensor Fuse?

P0121 - have you ported, done the bump stop mod ect to the tb? did you turn the inginition on with the harness disconnected?
P0152 - there could be your problem.
P0300 - what are you mods? could also be caused by the above code.

I have done nothing with the throttle body nor have I tried starting the car with anything unplugged.
Hopefully the mechanic will be able to solve the problem.
Could messed up o2 sensors cause misfires???
