Faulty Injectors - synergy 2 - Barnsley

DazBat · 29th December 2009, 10:25

Hope you all had a good christmas!

I have an MG ZT diesel which I have tried to install a synergy 2, on installation the engine ran rough and smoked a lot!.

Bigruss put the T4 on it and found the the cylinders were out of balance (MAF was ok)

cylinder 2 +2.4
1+3 around -1.5
cylinder 4 @ 0.

Could this cause the synergy not to work, or make the balancing issue worse ? Without the synergy fitted the engine runs smooth.

Assuming the injectors are the issue, does anyone know of a good place to get my injectors tested in the Barnsley area, I have spoke with Johndotcom who can sort me out with a new set of injectors, need someone who could test and fit a new set.

Cheers !

First of all, put loads of injector cleaner through the fuel system, that will help.. then...

Try leaving the MAF off (if it's a Bosch) then put the tuner on 3. and if thats ok, move up to 4 and try again, and so on untill you find a setting the car likes.. :lol:

Russ (and Keith) found my injectors varied a lot, but my car still runs very well with a Synergy2 fitted.

Won't tolerate the Synergy on any setting even off.

I have contacted Ron and am awaiting a reply.

James,

thanks for the reply, it was russ who tried to set the synergy up for me, we tried with/without the maf and different settings and no luck.

Also put 2 x lots of injector fluid through it prior to synergy fitting.

Cheers

Mine according to BigRuss were out... wonder if its a CDTi thing?

My dad says BigRuss knows what he is doing and so to anyone in Yorkshire.. use him!!

The Injectors do indeed give bad readings as out of balance on T4 when requiring replacement,
often accompanied by leakback which is generally the reason for T4 confirmation of worn Injectors.
I have sent the OP a few things to check which I expect Russ of course would already have suggested.
One of the Main things for smoke on a Diesel is over-fuelling which can be caused by the MAF or indeed the EGR or PCV among others.
Still a strange fault when Synergy fitted though and will be interested on Ron's reply as not seen purely this.

After changing my Injectors they were nearly all reading on or near "0" on T4 and fault cleared.
Has your MPG dropped at all?

DazBat · 29th December 2009, 16:48

Not noticed a loss in mpg, I has the PVC and ERG valves replaced before we fitted the synergy ..... once the synergy had been removed completly the smoking stopped.

Still need a local injector specialist if anyone knows of one.

James.uk · 29th December 2009, 18:27

Strange innit.......

I too will read Rons reply with interest..

My local tame mechanics tell me the usual "symptom" of a leaky diesel injector is the engine won't want to start up! lol..

That's a generalisation, not specific to the M47r engine..

Lets hope it's a cheap and easy fix. :lol:

Car has only done 50,000 from new, starts first time, revs freely, little if no smoke, since the injector cleaner has lost some of the hesitancy it had before.

No.2 Injector could have been like that from new (which isn't unheard of.

)

Just had an email from Ron, sounds like a possible faulty synergy (far and few between I hear), I'm sending it back tomorrow, I'll keep you all informed as to the results.

Can't wait to see the difference this unit makes.
