A slight "cough" / hiccup when in 1st gear.

All

Slightly odd "problem" but when in 1st gear just moving along at around 5mph at constant speed the car "cough's" difficult to describe but you just feel a little hesitancy which then clears, a little bit like you have just taken foot off the gas & re-applied & the car has jerked a little. A little like the car has hiccup'd !

Also when cold, approaching junctions, slip into neutral & the revs rise up then drop down again, fine when warmed up - wondered if the 2 were linked?
Maybe MAF ? Any ideas ?

Its an 02 996TT

Thanks

I had a similar problem with my TT when I switched to Tesco petrol from optimax-quick hiccup at very low speed very occasionaly-it went after a couple of tanks of the new stuff.

Interesting - I switched recently from Optimax to Tesco, had about 6 tank fulls now though so all should be ok. I seem to remember it did it before on Optimax though too.

this may be worth a try.

Interesting - thanks for this. I do suspect the MAF - not sure if i have the guts to try that DIY cleaning, I am the sort of person who can't put a biro back together once its taken apart !

LOL-I know what you mean-I may give this a try though-looks like a couple of bolts which should be easy enough-should be a good warm up for installing my short shift.

You are a brave brave man !

[rumplestiltskin]

egbert - which spray cleaner are you going to use? The one mentioned on that link looks like its only available in the US ?

I'll see what they have at the local hardware shop-non residue seems to be the most important thing.

Cool, let me know which you get - am determined to do it myself cos if I take it to an OPC they will just want to replace the MAF & charge £silly.
