EGR fault with new EGR.

[David l withey]

Hey people please help me.

I have a problem with the EGR works when wants to. The EGR is brand new even new pipe to EGR from the throttle body.

When I installed the egr come up map problem it rev bouncing in idle. I disconnected the EGR and it settled the problem just at idle revs at 1000rpm.

I kept trying the EGR and now and then works fine for a sort time then starts rev bouncing at idle. Even when it rev bounces it don't start doing that until I move it in first or second gear.

That can the problem be

Oh the Map is new as first thought that was the problem.

Could be the vacuum lines, are they the original ones? Cheap to replace and rule them out anyway.

All the lines are fine far as am aware mate. I changed a few but not many. I'll show you a video clip of it on YouTube in one or two days mate. Really is weird

I tried to get it to play up today but its been OK ish. It rev bounces for a second or 2 but then resettles itself. It was surging at intermittent times. I removed the rubber seal inside the connection and the clip clips on more than it used to be. I cable tied it to hold it tight up to the egr valve. The car works when first started. Then the code reader said i had map problem (p0106) I deleted the codes and turned engine off then back on again after a minute and works fine. With all codes gone

When I started the car later today was fine then map problem just deleted it turned car off then worked fine.

Am just lost tbf I know its not the map but something with with egr as when I disconnect the egr it works. I think might need to look at the wires tbf

Do you think temp sensor can make it play up if that's faulty.
