Vauxhall Zafira engine running lumpy with loss of power

Car: Vauxhall Zafira
Model Year: 2001
Categories: Running Rough, Starting & Power Loss
Hi,
I have a vauxhall zafira 1.6 on a 2001, I have had endless problems with it and i am feeling the strain on my purse now!
The car seem to be running lumpy, on 3 cylinders and loss of power, with the EML on and sometime flashing when i put my foot down!
I have replaced a few things.
Thing i have replaced -
* E.C.U
* coil pack
* spark plugs
* injectors
* temp sensor
* pre cat o2 sensor
* had brand new clutch

Even after all this it is still running like poo!!!

Any ideas? or anyone had the same problems and got theirs fixed?

thank you :)

First off, get it booked in to get a code reading. This at least will give a guide as to where the problem lies.

I bought my car a year ago and I've had to
Do a lot if things to it. I also have the same problem
As you and after calling the RAC out the first time I had a
New coil pack fitted that was fine until I needed
New plugs and leads but its still doing it but now I've
Been told I need a new catalyic converter which is going to cost me a fortune. So to save you some money maybe call
Out your breakdown so they can do a diagnostics test
And then you can go from there. Sometimes they will fix the problem or they will take it to a garage.

egr valve and the air flow are very common faults on these, you need to code read before you throw parts at it
