Thread: Eternity turbo lag

Mines a manual had had a similar experience when my MAF was failing. But they do seem a bit gutless below 1800rpm anyway.

I also have what appears to be a high rev missfire, subtle but it is there. I have checked the engine ECU there is no oil at the injector harness at the ECU.

So far I have checked nothing else.

Any ideas?

I don't have the foggiest notion about what could be causing the hi rev misfire.


My Td5 manual is as slow as a wet weekend below about 1800rpm. I compensate by keeping it between about 2000 and 3000 rpm where it goes pretty well. A Td5 is not the car to used to zip in and out of traffic methinks...:-)

The EGR is still there?, if it is this can cause that so make sure it's not clogged with muck, clean the MAP sensor(in the inlet manifold) anyway unplug the MAF and drive test it so also make sure that the wastegate is not stuck by grabbing the rod and moving it both sides, you must be able to push it toward the turbo about 15-20mm with some force then it should come back freely pulled by it's spring

Hi There,
EGR has gone, I'll check the MAF..... good idea. I've also de-catted the exhaust, thought that might have been a contributor. I'll check the waste gate opersation that was going to be my next port of call. If this is what it is thats fine, just checking that mine wasn't abnormally slow. My auto TD5 surprisingly seems "zippier", ah well, I'll check the MAF and go from there.

Thanks for the comments.
