code 34? egr valve or sensor
#2
if you apply vac to the EGR and the car doesnt stall out, your lines are likely caked with carbon. Remove the EGR and make sure it is not clogged. After that you would remove the EGR spacer fron behind the TB and clean it, followed by removing the intake manifold and doing the same.

ya it didnt stumble. i have the egr off right now and am cleaning it. which lines are you reffering to? also ill clean the spacer, and the intake looks like it has a lot of black gunk in it. but its a gt40 tubular, has always been a pain to clean. any ideas?

ok thanks adder. pullin off intake right now. hey im confused as to the egr piping? i see 2 lil rubber hoses go from egr spacer into a black pipe. i popped the hose off and the pipe has coolant in it and i believe goes into the water pump.which pipes? thanks

UPDATE
ok so i havent been able to work on mustang until now. i checked and cleaned everything.timing is at 12 degrees. no vac leaks, although i saw the vac guage go from 17in at idle and drop down to 12in for a little bit. really wierd. still idles so rough, like its gasping for air. i took it for a spin and at a stop light it will idle fine. wierd. if i give it 3/4 throttle runs perfect, if i floor it from about 2000rpm itll stumble and i hear popping noises. i came home, ran codes koeo 10, 34. koer 12 41 91. im frustrated beyond belief. plz help.
