Title: hesitating when changing gear
Post by: MV6Danny on 21 October 2011, 07:00:31
Hi guys. my 3.0l mv6 has started to hesitate when i am changing up a gear, its like it struggling for a brief second or like its cutting out and then it fine. Its only just started doing it. any ideas what this could be?  ???

Sounds like it could require the transmission oil changing and the transmission filter cleaning.

I've got a feeling this car is a manual? ???

May be worth checking for fault codes

Ok so i have just done the paperclip test and results were code 12? anybody know what that one means as its not on the list of codes and 74 which is Mass Air Flow Sensor Voltage High. Anybody know how to cure that? and would either of these cause the hesitation when canging gear? ???

Danny,

If you like, next weekend (not this coming one) I can pop up with some kit, we can take it out for a run and look at the live-data on the laptop?

It might also be a prime opportunity to look over the LPG setup, on your old V6.

I'm keen we don't begin any LPG installations, until 100% confident yours is running as it should be  :y

Good advice James, you don't want an unknown added to the equation!

Is the MAF on your old 2.5 the same part number / plug?

If so - we can try that too :y

Yes thats sounds like a plan to me james. you could come on sunday if thats convenient for you. Should be in all day. What is the MAF could have a look see if part numbers are the same as cars are the same year just different size engines. Will check haynes to see what it is. I will PM you my number if you like. :y :y :y
