Oh no!!!! Don't get Webby started on 0-60 times

I could post up over 5 yrs of data from my 3.0 auto, admittedly on LPG (so you'd need to add approx. 15%)

OP - have a similar issue myself (though no 3.0 to compare it with, unlike yourself!  )

Out of interest zirk, what will changing the MAF prove? Thought the MAFs weren't ever an issue on 2.5s always seeming bulletproof, only the later V6s for some reason seem to fail?

Check out my 'Stats' thread OP for some more info, if it helps 

It would prove its not a MAF problem, OP has almost like for like sitting on the drive so fairly easy to swop them over and see if the issue moves.

The MAF's don't always just fail, they can deteriorate over a time, feeding wrong info to the ECU.

Generally, 2.5/3.0 MAFs either work, or are catastrophically wrong.  But there can always be exceptions, so if a spare exists on a convenient donor .


2.6/3.2 MAFs by comparison do tend to deteriorate rather than fail catastrophically.

My two 2.5CDX manual saloons give about 29.5mpg over 2000 miles of mixed driving, my 2.2 manual saloon only gave 27.0mpg over a similar mileage. As discussed on different thread, earlier engines are more efficient.

Corection: the 2.5s are estates.

oh if its sitting there, well worth the 5 minute swap it is, agreed. 

Just checking if there'd be much point before I started to go hunting around for a spare MAF, that's all . Worth it if you've already got a spare, though, quite agree.

Strangely enough, Ive had 2 Maf's go, both on 3.0 MV6's, one gave up the ghost overnight and other was causing issues until I swapped it out.  I yet to have Maf go on a 2.6/3.2.

Having said, Ive yet to have a Crank Sensor or Oil Cooler go on 3.0, they've all been on 2.6/3.2.
