the Dizzle not so smooth
 
My AutoCdti seems not quite as smooth at tickover, a little but lumpy , bit ok when driving.

Had a bit of spare time today so had a peek with TOAF at the Injectors before doing a leak back test and eventually fitting the new Bosch MAF .

Got these approx figures for the Injector Correction.

At tick over around 750 rpm

Cyl 1... +0.97.
Cyl 2....-1.45
Cyl 3....-1.67
Cyl 4....+1.97

And at around 2000 rpm

Cyl 1... +1.47.
Cyl 2....-2.00
Cyl 3....-2.40
Cyl 4....+3.65

Anything to be concerned about ??

Cylinder 4 seems a bit suspect. Had mine on the T4 at one of our meets and was advised that the reading was a bit high around that high figure.As Jon said, put a dose of injector cleaner in and give it a thrashing.

Took my own advice and bought some injector cleaner for mine yesterday.---:D

Just in case it needs it .---;)

I use injector cleaner every other tank full in both the diesel and the petrol.

As your car is a diesel and you only had about 40 miles of diesel in it you are taking a chance that it might stop altogether.

The general advice with a diesel is to NEVER let your tank fall below a quarter full. --If the in-tank pump is dead you might be starting, with your rough tick over, to be experiencing the start of the under-bonnet pump failing. ---:eek:

I know my car after 17 years, :D,. It's pumps are all ok and often gets down to low levels ..
It will actually do over 20 miles after the range reads zero.:eek:

Got to 25 mile's and filled up .
Don't panic Mr Mannering ..

You're a brave man Chris and if I was handing out medals you'd get the top one for fuel pump bravery.---( When I think about the many many tales of woe about low fuel levels and dry burnt out pumps.-----:bowdown::bowdown::bowdown:
