Help!

[barry_shepherd]

Hey folks, got a bit of a problem here. Was driving the car this morning and it seemed pretty sluggish. Felt like it was going to cut out on me at some points. Whenever I put the foot down, it wouldn't pull as it should, instead deciding to kangaroo me along the road for a few seconds before picking up. Interesting to note that the BOV didn't go off when at around 5-6k in 2nd, don't know if that has anything to do with it.

It's had a new clutch 3 months ago and the brakes aren't binding as I thought that was the problem but they seem fine.

Any ideas? Worst case scenario? I'm completely stumped.

Cheers,

Leaking or perished hose if the bov is not going of or the MAF.

Check your vacum hose going to he dump valve mate. Do you have a boost guage? If so maybe the T piece you use to break into the vac hose has come off there??

[barry_shepherd]

The BOV did go off most times, but there are times when it didn't, maybe there wasn't enough boost in the turbo but that seems unlikely. Will need to take it out later on and see if it's still doing it. Rather annoying I can tell you.

Have not got a boost guage unfortunately, I'll have a look at the vacuum hose, take it that's the thin line that runs into the BOV? Not very techincal at these things

yeah the va hose is the thin one that goes to the bov.

does it rev freely on idle?

does it rev freely on idle?

It doesn't actually, I did notice that. I turn it on and it sits at just over 1k and then when i noticed the problem, pulled over and it was below 1k and kept rising and falling every few seconds. It drops to the point where I think it's going to cut out then picks back up again. Daft thing! What could that mean?

Edit: Just read your post properly, do you mean can I rev it normally on idle? I'll give it a check and get back to you

OK, I'm stumped! Just took it for a spin, no troubles, no coughing, kangarooing, BOV working fine etc...

Stupid damn machine!

Thanks for the advice though chaps, car must have just been in the huff!

What year is the car? This sounds like your maf is playing up. Did your CEL come on? If it's a classic look on scoobypedia and it'll show you how to read the fault codes.

It's a Terzo mate. What's a CEL? I suppose the fact that I didn't see anything come on would suggest that it didn't, but you never know.

If it is the MAF is it an easy fix or will it hump the old credit card?

Could be down to the sh@t weather.. I cant remember, do you run an induction kit on the car, or even a Panel Filter with the resonator removed??

The hunting sounds like a MAF fault, its not mega expensive and is a job you can do yourself.. or a local garage could do for a couple of quid, takes minutes. The MAF is the sensor at the turbo side of the airbox/induction cone, could try taking the sensor off and giving it (the thin wire in the middle of the pipe) a blast with brake cleaner, I'm sure that helped my old MY99 when I did it.

Theres a wee pic to show which sensor I mean.

It's running a panel filter mate, not sure if the resonator is off though? TBH, don't even know what that is haha! Would it be pretty obvious is the MAF was needing a clean? I mean would it be visible?

Cleaning the maf is hit or miss, imo if the maf is the fault your better replacing it to be on the safe side.

CEL is Check Engine Light you would see this as it's in the instrument cluster low on the rhs.

When I replaced my MAF it was £200 and that was at cost price.

Look here for info on how to read fault codes and diagnose the problem

Diagnose fault codes

[barry_shepherd]

Well I gave her a good warm up this morning and she's running no bother. Am going to stick it in to the garage for a wee diagnostic just for peace of mind I reckon

Thanks chaps
