hesitation...where?...what rpm and speeds, and how much gas is in the tank when this happens

i doubt its the fuel pump and the fuel pump is located in the fuel tank. you could have a bad DPFE, dirty maf, vacuum leak and quite a few other things...hell could even be a little carbon build up.

The engine light is on cause my cat is hollowed out (bad mistake) it has stalled going down the road twice when i pushed the clutch in and the hesitation starts when i rev it and the car is moving i can feel it all the full tank or an empty tank it doesnt matter it just sits the and shakes and i got an engine ics clean out didnt fix it and a new fuel filter didnt work, the hesistation does it in all gears they said in here its the fuel pump and i want to get a new one a fuel injectors. But i just want the idling to stop what its doing i spent $130 on a new maf from a shop didnt fix shit new plugs wires still does i just want to to run smooth ,and how much does egr cost and why would that effect my idling?

not the egr, part of it, the dpfe sensor usually goes on the focus, plugging the port off the dpfe can help check the problem. i just read you gutted your cat...thats the cause right there, the 2nd o2 sensor is probably shot. just get the car scanned for codes and to pick up a mil eliminator, www.myfordperformance.com

i think it is the d.p.f egr sensor i would replace it. its around $30 symptoms are rough running lack of power surge or poor fuel economy if you need a cat i have one that has 200 miles on it i 'll sell it to you for $150 email me at b_alamorian@hotmail.com

why gut the cat? why not just junk the cat in favour of a replacement pipe, and then just stick it back in for MOT time?
