Hi everyone sorry if this is not where to post this I am New, I have a 2004 jetta BEW tdi, last week I was driving on the highway at about 70km/h and I lost power I pulled over and the car stalled it would crank but not start, I towed it home got to look at it found the egr full of carbon, I cleaned it up and pulled the intake elbow tube off, now it starts but stalls if I put the intake tube back on, I have very little exhaust coming out so I drilled a hole pre cat to check if the cat was plugged, still same issue, very little exhaust coming out of the hole I drilled as well, I'm pretty sure I have an air restriction somewhere or something like that I was just wondering if anyone had any insite on where i should be looking for it , with the elbow off it idles fine but as soon as i put it close it stalls out any info would be appreciated
