today when i took my car for a test drive at 7.5k rpm my car jerked foward and lost power (it felt like i stepped on the brakes). i recently put in a itr header and a cat(didnt have 1 b4) i havent reseted my ecu yet but was wondering if that would help my problem. thanks

 

work bump

 

have you tried to resetting the ecu yet?? try it and come back with some info..

 

If the check engine light is off, i'd check the timing belt. If it's on, check the codes and go from there.

 

i heard something moving around in my brand new cat.. it looks like the back part of the internal cone as broken inside. would this be a result of me losing power due to unconstant airflow??

 

it looks like??? did you take your cat out or something to check this??

 

yea i took out my piping at work and looked at it. the cone broke inside somehow(only the second half of it) but i didnt have time to take it out yet.

 

you should try taking it out i've seen a thunderbird take a **** when the cat got stoped up somehow... if someone reads this dont ask how... cause i didn't ask the redneck dude i just seen him take it out for his mother..

 

A plugged up cat, or not functioning one, will definitely make you lose power. What type of cat did you put in??? In that case, replace it.

 

i had a "brand new" magnaflow cat. i took out the remaining pieces of the broken cone and now it runs fine. planning to replace it soon also.
