my car seems to have lost all the zip and pick up it once had. what could cause this? i triedadvancing the timing a littlle bit, but no help. could the tranny cause this if it needs new fluid and filter? it used to kick the tires well enough to humble many mustang owners and do kick *** burnouts, but now nothing. a little chirp if im lucky. powerbraking barely gets anything. please help!

 

what mods? need more details. any funny noises? engine shaking?

 

cars 12 years old, maybe your cat is getting clogged, maybe your fuel system is dieing out

 

90 Lo3, new highfow cat, 3" pipe, flowmaster, MSD cap, rotor an wires, open air element.

dont think its the cat b/c its brand new. how can i heck out the fuel sysem to see if thats the prblem?

 

I don't know how to check everything, but the easiest thing to do is pull the air cleaner off, start the car, and make sure the injectors are spraying good and their is plenty of fuel

 

Check ur firing order and that the wires are fully pluged in. good luck.
