2.0l 16v Cold running and crap mpg !!

Recommended Posts

My valver Starts fine but when cold it stutters and judders at low revs whilst driving .All is fine as soon as it is warmed up .

Is this over fuelling as my car tends to drink a lot of juice aswell. Any pointers as to what it may be?

 

And yes I have used the search ..........

 

Cheers

2.0 according to the thread title.

 

What do you call a lot of juice? My 1.8 16v barely tops 30mpg and it's running fine. I call THAT a lot of juice!

I get about 280 out of a tank with mainly motorway miles !

check water temp sensor on head. Worked for me! I had similar symptoms too......

 

Is this the sensor with one wire or the four wire one ?

 

P.S. 2 litre

Yep, that was the pic I posted multiple times recently.

 

280 miles per tank isn't far off for a 12 gallon tank, but yours should have the 15 gallon tank.

I don't believe that the temp. switch could affect the fuel consumption to that degree though. Heavy fuel consumption is usually related to a dodgy Lambda probe or wiring, but that also (usually) results in poor running when warm.

seems to be a common problem on the 16v's! wish i'd got a g60 now (or do I.....?)

The 1.8 16v is the only Corrado I'd own as it's the simplest.

Thx for info Jimmy !! :wink:

 

I will change this sensor as a matter of course.

 

bcstudent I have recently replaced leads, lambda, fuel&oil filter, dizzy cap,air filter, and none has made any difference.

 

It is so annoying when you don`t know what it is.... aaaaaarrg

The car runs really well if anything a bit faster and pulls better early on in the rev range. It may be timing or fuel delivery valve or injector related or something beyond my means to investigate........

I think I might have to book it into Stealth for a health check-up.

 

P.S. Yes it is 15 gallon tank

No worries M8! Actually, it was vince at stealth that identified that the sensor was playing up when my car went in for a service, just plugged the good old VAG-COM in!
