You'll get infinitely more help if you describe the problem and ask for advice on the forum itself.

could be coil pack,how long did it start after top end was rebuilt

plus, any codes?
Title: Re: 4-Pot Petrol Specialist - Advice Needed
Post by: Sam Burton on 13 January 2013, 19:52:54
Computer says nothing Not one fault code the engine management light isnt on. it ran fine after the head was done, its just got worse over time, their was an air leak which was a seal on one of the injectors which was replaced with Vauxhall parts but although it fixed the leak, its made the thing lack power low down Checked cam timing and now it wont rev over 3000rpm?
Title: Re: 4-Pot Petrol Specialist - Advice Needed
Post by: Broomies Mate on 13 January 2013, 19:55:43
Check codes again!  If anything, you would have had old codes stored from the air-leak.

How are you reading the codes?

The Old paperclip test is that okay? or should i try another
Title: Re: 4-Pot Petrol Specialist - Advice Needed
Post by: martin42 on 13 January 2013, 19:58:35
i would say coil pack in that case,might be worth just removing it and checking the condition of it,and make sure the rubber boots are ok

Can sensor will put the auto box into a tizzy and cause misfires and lumpy running. 2.2 prone to this fault.

Ill try pull it out next Saturday the trusty DTi keeps chugging along so i keep using that :) interested to see if its a genuine Cam Sensor would this cause these problems?

This is the pricing I'm getting for a 2.2. But for some reason not a camshaft sensor for the DTI on the site....

Have you checked timing for misfire? ECU will throw an 0340 if it`s out. BTW RPM cut off point for dodgy cam sensor is 4500

I dunno i got some little Card thing from MIGWEB

the timings been checked and apparently all is well but like i keep saying obviously ruddy not otherwise id be able to drive it lol

Do not change anything until you've had the codes read, it will only complicate matters.

2.2 petrol needs a code reader. No other way to read DTCs on that.

Having all kinds of trouble code reading the 2.2 Auto

Quick question though would a Duff Lambda Sensor cause te auto box to go into limp mode?

Mate bring your reader maybe one out of three should read car fault=cross timing off list and cam sensor(GEN VX) and reckon its ECU myself due to 2 people tried to access fault-EML is on sometimes when you start sometimes not? Eml can go out =spanner light comes on?? Gave up myself cos needs Tech 2 and well rest is history mate Just let me know what problem was Eventually when sorted=reckon get code solve problem pretty quick if not worth it in parts mate TBH.

Do you think general ECU or Gearbox ECU

Post by: symes on 20 January 2013, 00:12:00
Dont know havent got tech 2 and its a DBW which means drive by wire BUT should be Dont Bloody Work!!!! Useless turd of an idea that electrickery to replace simple cable-Faggots
So havent a clue which ecu or if something simple causing it-all migs from after 2000 are b***** you cant do paperclip test and need computer to just find fault-if you lucky   Now wait for rants mate - trouble is what i say is true and no one wants to admit it
Thats what I said to previous owner he had mate who owns garage told him to Tech2 the ******r  Funny thing is I took for drive and all good-went to old mans-next day F U B A R go figure? on that then-fitted vx cam sensor as everyone and thier cousin said=cam sensor=B*****x same
best bet is take to garage and Tech2 at least it will get it then-Had people contact me privately over their own cars and soon as say DBW or 2.6 tell them garage +Tech2

Im bloody awful with Petrol lumps but the 'dangle berries' with Diesels lol Help needed me thinks
I'd go back to basics and start by checking for a spark at the end of each lead/coilpack, then re-check timing (it may have slipped since 'symes' last saw the vehicle).
It may also be worth checking all the fuses, which pins did you short out at the diagnostics plug?
Does the e.m.l. come on with the other lights at initial start up?

There is no cam sensor on a 2.2 Vx. diesel.
Also any code reader that can talk to a Vx. diesel should be able to communicate with a 2.2 petrol easily.

Any glitches in the engine ecu, gearbox ecu and abs ecu can causes engine and gearbox to limp.  All 3 ecus have a close relationship, so when one has a monk on, it can affect the others.

It really does need to go on a code reader capable of readign these 3 ECUs.  Anything else is just guesswork, and that then, aside from being expensive, further complicates matters.


As to DBW, nothing inherently wrong with them. Most are robust, and the ones fitted to Omegas are very robust.  In the 9yrs or so I've been active on various Omega sites, I think I've heard of 2 failures. It is worth cleaning them every time you do the breathers (ie, annually, or every couple of years if its always used for longer journeys only), but this is no different to the cable operated ones.
Title: Re: 4-Pot Petrol Specialist - Advice Needed
Post by: Kevin Wood on 20 January 2013, 10:07:35
.. and, to add, it won't be either ECU, before we go down that route. They are incredibly reliable. I can recall one or two faulty engine / gearbox ECUs in 6 years of diagnosing Omega issues.

As said, until you know the codes raised by all 3, you are  in the dark.
