Recently I noticed that my car hesitates under acceleration, it kind of shudders from about 4K to 4.5K RPM and then goes back to normal. This happens every time I accelerate. I've done a search on this forum about this problem and it seems very common. Unfortunately, I couldn't pin point what might cause this problem to occur and what's the necessary fix. I really don't want to start changing out random parts until I find the right one, since as we all know parts for our cars don't come cheap.<br>Looking for advice and what to look at, thanks in advance.<p>Don't know if this might have anything to do with it but a few months back I got the RICA tune and installed a custom short tube intake on the car. <br>2004 S60R

Re: Hesitation, loos of boost (Logan750)

Well, if you've been searching, if that 04 does not have the upgraded VOLVO software from late 2004 AND you add a tune, it just makes it worse!

I'm not entirely sure but I think all the software should be up to date since this was a leased car prior to my ownership and was serviced frequently by the dealer. Being at the dealer I have asked about recalls that had to be performed and was told that my car is up to date with all the recalls.<p>I'm assuming that the TCV is failing me and causing to lose boost.<br>

Mine also had the hesitation issue and was fixed with the ipd tcv.

Re: (volvofla)

My TCV was shipped out from IPD yesterday. Same problem with the stutter at over 3k RPM. I will be pulling the MAF today to clean it as well.

Re: (Logan750)

I like that they got 5 point star tamper proof torx on the MAF instead of the 6 point tamper proof I bought. Who sells the 5 point? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <p>Edit: IPD should put together a Volvo Specific tool set. All the little crap you probably don't have in your tool box. <BR><BR>
