I've had something strange happena  couple of times today.  Started it from cold and warm after sitting for a while.  All's fine for the first 30 seconds, then it starts misfiring and trying to stall, then after about another 30 seconds it's fine.  Any ideas?

[Mike Pavelin]

Crank sensor or upstream O2 sensor.

[craigderby]

Is there anyway to test it?  Or should I just take it to a garage?

[Manda]

See if you can borrow a working one from someone to try, IIRC they're about £80 each.

[Mike Pavelin]

Look at the volt meter on the dash. You should see about 13.5v if the alternator is charging.

[craigderby]

Voltage gauge is spot on.  

It only does it for about 30 seconds and then it runs perfectly

[craigderby]

If it is the crank sensor, is it likely to just packup?  I'm suppose to be greenlaning tomorrow and don't really fancy breaking down in the middle of nowhere

[craigderby]

Where is the CPS?

[isle of man]

i believe (from memory) in the 2 o'clock position on the back of the engine as your looking at it.

The cars still playing up.  It's been in today and the garage can't find a fault, anyone got any more ideas?
I'm starting to get a bit fed up with it, so if I can't get it fixed in the next couple of weeks I'm going to part-ex it for something else

[Mike Pavelin]

Has it been scanned for fault codes? Dif you take it to a dealer with a scanner that will display sensor outputs while driving? Sometimes a sensor can go faulty without being out of parameters so wont generate a fault code so you have to monitor their performance as the fault occurs to find the culprit.

[craigderby]

It wasn't a main dealer, to be honest I can't afford their prices.  
I'm thinking I might get rid this week.  We're suppose to be going away next weekend with the caravan and I just don't trust it to get us there.  I'd rather take our old Landy, at least I know that'll work, it'll just take twice aslong to get there!!!

[german guy]

it is possible just the coolant temp sensor reading wrong at a certan temperature like 15 C 16C 10C 17C until it gets his reading right
that will not show up as a fault but it will have cold start probs

[craigderby]

It turns out it's an O2 sensor.  It went into the dealership last week, but the part won't be in until sometime this week, so we've had to cancel our holiday  

[greggmo]

well if you have had to cancel yer holls just come to cheapfest and party with us.

[craigderby]

Tempting mate, but it's going to cost £210, so that's all my beer tokens gone for this month  

[greggmo]

£210 are ya mad? just order the part from lighthouse and bring it to cheapfest and we will fit it for ya for nothin.  http://www.4wd.com/productdetails.aspx?partID=8167  thats £35 mate. i recon you will get one off lighthouse for about £50ish. dont get ripped off by the stealers mate. just by one and we will fit it for ya.

[craigderby]

Cheers for the offer, but I left it with em for the part to come in.  It's sat down there with the origanal part removed.  
To be honest I know they're a rip off, but I needed the fault diagnosing and had no other way of doing it.  They been quite honest about the cost from the beginning.  Fingers crossed it'll be done tomorrow

[craigderby]

Hooray it's fixed!!!
