got a live test today

[GH421]

A mechanic gave me live readings of my injectors

Injector 2 was reading much higher than the rest at 1.4 (not sure what it's measured in)

The rest were around the 0.6 mark except injector 4 which was 0.2

He says injector 2 was running higher to compensate for injector 4 and was the cause for the slight smoke on acceleration

Is it worth getting them changed? What's the price?

Car is W203 C270 Cdi

I'd be tempted to give it a good dose of injector cleaner before I did anything further.

I'd be tempted to give it a good dose of injector cleaner before I did anything further.

And ... Give it a good thrash at the same time.
Works wonders with fouled injectors
