Hi.

today i was checking the injectors since i have a p0204 code, and the motor was reving up and down and sometimes dying when starting.

but i noticed that the egr valve was moving, like dancing, so i checked it and the egr line that goes to the intake was broken.

so im going to replace it, but i wanted to know that if besides the bad injector could that be the reason of the hesitation and the engine reving up and sometimes dying also it do sounds like when air is being sucked in the engine from that part.

this is the line im talking about it goes from below the intake to the egr valve.

Not often we see a P20* here. Install a new EGR tube and clear the codes and see if the injector code comes back. Be ready to replace the #4 injector though. In the mean time, inspect the connector and harness for opens.
