no power


hi got a 98 gt mustang,with a 2000 4.6 motor,with approx 72k miles motor idles fine but when you put under load it has no power, motor lays down. i've replaced the fuel pump and filter, any ideas what i need to look for??

Try cleaning your MAF so that you get an optimum air/fuel mixture.   And, while you are at it, replace the stock air filter with a K&N.   Welcome to the site.  Drag up a chair and stay awhile. 

if it was a maf his idle would be bad also...duh... try your TPS if not that check all your plugs and wires..most likely it will be a bad plug or wire

Sounds like a wire problem to me.
