16v... heavy fuel consumption and intermittent ..EDIT !!

[rayb74 0]

Hello all !

First of all the 16v(9A) does not have a MAF ? it is VR only I think.

 

The story is this .... in the summer I gave my car a decat and a service then took it to vince for a RR sesh and it pumped out 147 BHP and vince said it was ok. All was good it ran like a dream I am very happy chappy.( Thx Stealth!)

 

My car has always been a drinker but LATELY..... It has started to drink more and I am noticing that sometimes when I put my foot down it really pulls and other times it seems a bit gutless, lacking something.

 

In the summer I replaced plugs, fuel filter, air filter, oil, Lambda probe, oil filter.

 

Can any of you please let me know what you think it might be? The only fault codes I can find with vag-com is abs sensor !!

Anyone ??

Dizzy cap, rotor arm and leads are worth doing if never been changed before... maybe look for signs of arcing at night by spraying a mist of water of the leads if you think it's ignition related...

I would have suggested the Lambda probe based on the comment about increased fuel consumption, but I see that's been changed. The fuel mixture richness is controlled by the differential pressure valve on the engine side of the fuel distributor - that may be worth a look. Another simple things to check is the full-load switch on the throttle body.

 

That's about all I can think of regarding fuel mixture. The KE-Motronic system is pretty damn simple so there can't be *that* many candidates for the fault.

Thx for comment guys !

 

I changed cap, rotor looked ok. I never did change the leads though.... bought some but they did not have the adaptors on the end and were too short so I couldnt fit them ........ will buy a new set anyone recommend some good ones I got a GSF in town .
