running prob

[dam088888]

When I'm driving and change from 1st to second then put foot straight down it like kangaroos till I let off and so it smoothly same if its parked up and pop the bonnet and rev it by hand short and sharp its like its holding back or spluttering at first. Need to change alternator tensioner as its rattely at the mo so not sure if this would affect it but its fine if you change gear and slowly go up the revs anyone got any ideas

Boost leak faulty MAF 

Any fault codes?

[dam088888]

Not plugged it in yet also unplugged maf still same to be fair does sound a little like a air leak from some where but its fine if you get on the throttle smoothly only happens of you put foot hard down after changing gear straight away

[richw911]

Have you done a throttle body clean?

Sounds like too much air not enough fuel at that slit second check for split pipes as rich said boost leeks etc

Read some where it could be temp sender now I changed it not so long ago for a xheap ebay one well in the end it turned out it was stat so i kept the gen one. So after reading it could be that I stuck the gen one back in and took for a spin and seemed ok so ill see how it goes. But could temp sender cause the prob I mentioned
