i have a 97 with a 4.6 romeo. i have changed everything i can but have no power. it runs right no miss and all vacum hoses are connected. but still no power. need help plz!!!!!! really geting mad at this motor

 

Are you sure the transmission is not the problem?
Check your brakes too to see if they are really hot after driving. Sometimes the brake calipers or master cylinder will lock and that will feel like no power from the engine.
The engine may be fine.

 

Have you cleaned the MAF sensor?... More details of all that you have done may help us diagnose your problem

 

Lots of things come to mind...

Fuel Filter, MAF sensor, clogged cats (don't always throw a code right away), as already mentioned, brakes, Tranny, the possibilities are endless... Or so it seems when it is happening to you...

 

the only thing i havent replace is the maf. im changing it today. already gutted the cats. and the brake are not binding. thanks for the info guys really do appricate it
