Either that or I could buy a new MAF sensor, go to TB, get the readings of kg/h at high idle (2400 rpm). If it is "faulty" then swap it clear the codes and retest. Should be good to go.

If not, then I can return the MAF sensor and get my money back, nothing lost.

If the MAF sensor is faulty I'll need a new one soon enough I reckon don't you?

Go on ,get your hands dirty

Just to let you know that last saturday I had my EML come on after filling her up with Tescos 99 RON rocket fuel and doing a 180 mile run non stop immediately after filling up.

Got the 0170 and 0173 codes,after a 2 hr stop but the car continued running perfectly and whilst having the light cleared by Mark we found the codes had cleared themselves.

Running on Shell now and wont be using Tescos again.

I have been known to use Tesco 99RON fuel a few times. Do you reckon that it could have damaged (clogged up) the MAF sensor?

I always run on the Super Unleaded fuel and tend to use BP when I can.

EDIT: That was a really dumb question. Fuel can't clog an air sensor can it. Dolt!

I just called my Vx stealers this morning and they have offered me one for £130 rather than the full retail of £180.

This rate is because they know me and always give me TC price discount rates on whatever I buy whether it is listed or not.

I'm just going to buy a new one out of frustration and to KNOW that it is fixed. It will be on my car by 2pm and the O2 sensors will be back behind the main cats as before.

I am doing this on the strength of the diagnostics work that Kevin did to Keiran's car this weekend.

I'll be driving to Leicestershire for a couple of days, so that should prove this one way or another. If it doesn't I wonder if I can take the MAF back as "unused"?

[Kevin Wood]

See Kieran's thread. I can pop an ELM reader in the post if you want to double check before shelling out for a MAF.

Normally, stealers won't take back electrical items, IIRC. :-/

Having just received a very welcome PM from Kieran, I have just ordered a MAF sensor for £33.50 which will be here this week.

That's £100 off what I thought was a good deal and £150 less than the retail price from Vx.

No bl00dy wonder they're called "stealers".

Thanks Kieran and Olympia what a STAR!

I know what i posted was not really that relevant to this highly technical thread, just wanted to point out that I had this problem and it was something totally different to what is being discussed here.

Cheers

This seemed like such a good idea at the time, but despite reassurances that this would be sent so that it would be with me by recorded delivery on Thursday before 1pm, I still haven't seen hide nor hair of it.

I'm beginning to wish I'd just spent the extra money and had it done and dusted on Monday.

False economy? Perhaps not just yet considering the saving, but I'm not best pleased. If it isn't here ON Monday morning I'm canceling, expecting a refund and off down to the stealers.

Very interesting been watching this thread with interes, as I reset my codes but after a few days EML came back on again, so if changing the MAF works, then the samejust might solve my problem, will wait for the results

Right the MAF sensor arrived today and I fitted it this evening.

I took it out for a run for about 50 miles and BL00DY HELL! it is like a different car. The pedal is so much more reactive than it was and you could almost feel it stutter before it went. By the latter half of the run it settled down and really began to run much better; it actually gives you a forceable shove in the kidneys when you floor it from 100.

I'll be down to clear the EML light tomorrow morning and keep you posted.

If that stays clear for a week then I'll revert the secondary lambda sensors to behind the main cats.

If that then keeps the dreaded 0420 & 0430 away after a couple of weeks I'm considering a set of standard 3.0 front pipes to remove the pre-cats altogether.

22 re starts, blimey! Presume its learning? I take it The car now ticks over as it should? And now goes like snot by the sound of it?

It's a bit of a slow learner, but it's good at PE

Keep is posted, as if the 0170-0173 codes stay away then a new MAF maybe the answer to my EML aswell as Bob.dent aswell, as he has the same problem (or at least I think he still does)................

Interesting about the learning bit, as if I reset the codes again, the car takes a bit of time to run normal, but a lot quicker than at Newent, probabaly cause all new sparks and DIS packs though

Ironically enough and unlike yours, resetting the DTC codes on mine made virtually no difference to how the engine ran in the very short term.

The car has always run sweet as a nut. I was getting the 0420 & 0430 which was the "tired pre-cat" message.

I moved the secondary sensors back to behind the main cats.

At around about the same time (entirely co-incidence, I am now led to believe) I started getting the 0170 & 0173.

But throughout this time the engine has run smoothly until last night.

Let's see how it copes with me and my right foot today.
