Title: Engine trouble
Post by: Lampynoiseboy on 14 June 2012, 11:36:50
Hi All

My mig has issues. Last week or so been a bit slow to start, and last few days there's been a bit of bunny hopping. Rev jumps between 1 & 2.5k, no power (or intermittant), stalled twice. Has only happened 5 times in a few days b ut don't want it to get any worse!

Friend has a snap-on Solus reader, returns the following codes:

0172 fuel trim bank 1 malfunction
0173 fuel trim bank 2 malfunction

Any ideas?

Check the idle air flow reading when warm, my betting is that its either low or high.

Get someone who knows what he is doing mate with either a tech 2 or similar to check it. I had the exact same codes I promise you. A MAF sensor cured it.
The Master is very rarely wrong :y

How much. I assume you mean for a MAF Sensor? Vauxhall about £140. Cavectra where I will be getting mine £90 ish..
Although one of the breakers maybe able to help. Typical I had one here up until a few weeks ago :-\

Rather?? Since when did the s/w recognise the irish f-word!

Anyhoo, can get one new for £140 + vat

Anyone beat that? 2nd hand maybe?

Cavectra is in Greys Essex so maybe not far from you

Yes. You have to remember Vauxhall don't make their own parts. The genuine MAF Sensor would be a Bosch. The one you buy from Cavectra in Grey will also be Bosch and identical :y

I would though like I said earlier get someone with a tech 2 or similar who knows what they are looking at to check your car before buying anything.
What "The Master" which is Mark DTM himself says about the MAF is exactly what mine was doing, also I got the exact same codes as you have posted.

Thanks mate

Unfortunatley I don't think anyone with a tech 2 is close

I was dowm your way at the weekend too :(

It was working at the weekend! *facepalm*

Well

Having had my guy read the codes as stated earlier, forgot to mention he did pull some bits off & put them back again. yes, I know that's vague, but I know less than nothing about engines. His first suggestion was also MAFF sensor, but he wasn't convinced hence the post on here.

However, since then it's been perfect, so guessing it was just loose or had shite in it?

Post by: Lampynoiseboy on 19 June 2012, 18:27:40
And he does normally know what's what straight away, was just unwilling to spend £140 of my money without being sure!

Fair I thought.... :y

Any thoughts?

Still playing silly buggers, but seems to be only when under a 1/4 tank of fuel, keeping it over that makes it behave.

I'm thinking fuel pump, any opinions for/against?

C0uld be dispack ... that would give intermittent performance similar to MAf sensor going ... I had the same on mine ...codes were saying MAF but it turned out to be dispack and by the time I got it out you could clearly see it was buggered... so if you have a spare 2 hours and don't want to waste any more dosh you could take out the dispack and check it

although the evidence with the extra fuel in the tank points away from that ... Blocked fuel filter/ fuel pump ???...I would still check the dispack

3.2 doesnt have dispack,has a coil pack per bank.worth doing the usual visual checks of coil packs,plug wells etc. Depending on service history,may be worth changing plugs,fuel filter etc.
Ideally a tech2 session to save on guesswork. Did I give you a number for a bloke local to you ?
