damn, the only thing i can think of are bad motor mounts ( couldn't be...), bad ignition system (sparkplugs, wires, coils) bad cam position sensor, and bad fuses. i'd take it to a shop to pull codes. just cuz you don't have a check engine light, you might have pending dtc's (diagnostic test codes).

if you didn't disconnect the battery terminals when the wrench hit the posts, then you might have melted wires. check in the engine bay all the way to the ecu under the passenger side kick panel. happy hunting. hopefully it's nothing serious.

 

I just installed the same SRI, and the car is jerking soppratically, I also ran my original box over by accident, I am going to go tomorrow and get a replacement, and put the stock setup back on. This has got me scared to death.

 

I know what your problem is. It is something with your Mass Airflow Sensor. Check your connections to it and make sure you have it plugged in. You should also reset you ecu by disconnecting the battery for a while and reconnecting.

Ok guys are for mine. I think it might be the spark plugs, my friend told me that would probably be the best bet. I probably fried them pretty good. I guess I will open her up tommorow and check them. BTW does anyone know where i can get some AWESOME sparkplugs and sparkplug wires (BRAND AND SUCH).
