Testing D5 Euro4 injectors

amazighman · Jun 25th, 2022, 19:59

Hi.

My car still runs bad at time , just came back from a short drive , the car when crawling seems to accelerate and decelerate itself , engine like surges and then comes down.
Idle was a bit lumpy too.

I did a Leak off test , which came back good , all injectors less than 30ml per minute.

Is test on Vida better way to find a bad injector?
Or bench testing is the only way forward?

Hi
There is a test in VIDA that cuts the injectors one at a time. You can compare the rev drops which could possibly point towards an individual injector?

I ll look into that , I haven't got Vida but hope to find someone in Burton on Trent that has one.

I am really getting fed up with this car , I noticed it also has like an exhaust blow sound like d-d-d-d on idle , its coming from somewhere around air filter...

I got a worry ot could be exhaust back flow because of Bad cam lifters
