Recently having a problem not sure what it is....I have done some work on the car including a tune up, plugs etc....Dp and new exhaust system and tune, and I have been hearing a louder than normal hissing noise and on restart as well as after driving a 1/4 mile down the road, it seems like it is not getting gas, and then car dies unless I sit still and once it gets going its ok. I first experienced it earlier in the week in normal driving. It is an 04 R w about 60k miles.....I am not getting any cels or anything, just a stuttering at a hot start and when I turn on the ac it starts to idle rough. I also called the dealership to ask about doing a diagnostic check and they said w/o a cel they don't know where to start and can't tell me how long my car will be there! Any suggestions would be appreciated....<IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> <p><br><BR><BR>

Re: New Problem w 04 S60 R (coolbob37)

Um, the dealership should *not* tell you they can't do anything without a CEL. It sounds like vapor-lock (a rarity these days). So I'd say on the R, it could be a fuel injector, fuel pressure sensor, fuel pump check-valve, fuel pump, but more likely something with the ECM. The dealership should know that they cant check for needed software updates *without* plugging into Vida, which has little-to-nothing to do with the CEL (which is primarily for emissions system purposes). I experience these same symptoms, fwiw, and have ruled out injectors, fuel pump and filter, MAF, plugs, tcv. Im taking it in for a needed ECM to BCM communications fault software update, which Im hoping will cure a couple of things. If it cures the heat-soaked stumble on re-start, I will update this thread as soon as it's verified on my end. There seem to be ECM updates that take the car from running like total poopos, to nearly or better than new. Others have experienced this, on this board. More soon, hopefully.<p>The MAIN think however, is that the dealership is the only place, for the most part, where they have access to all the modules. Most faults on the modules wouldn't make it to lighting off the CEL if the fault doesnt effect some emissions component or sensor in some pretty significant way. So your dealership sounds liek a typical Volvo dealership - clueless. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0">

oem plugs?<br>Volvo's don't like aftermarket-plugs.<p>Don't blame Volvo ... you went the dark side and got a tune <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0">

Could still be one of the plugs is bad ... my next step would be downloading the original engine-sw so you know the tune is bad (or not).<br>A good tech would say they can't diagnose a tuned-engine because they have no figures to start with. We 1st must reload the ecm but it will cost you.<br>(that was what I ment with you went the dark-side).

Re: New Problem w 04 S60 R (JARMO)

I doubt that a good tech couldn't test the car w everything just the way it is. Original specs to start with? If I have to reload the ecm or whatever I must have a real problem....It would take more than that to blow an ecm and I'm not a rocket scientist...There is no dark side.. any "improvements" I have made are only to bring it back up to original european specs not some watered down american version of the car. I have only made things better and not worse as you are implying. They don't have to completely breakdown any other kind of high performance car no matter what kind of car it is. The R is built for performance dude. If it is a high performance car it should be tested its current state. If you detune the car and take it in, then it will be tested in its detuned state not the way it is supposed to run now..The plugs are fine and I'm sure its just a minor problem. I really thought that people knew what they were talking about on this forum and that I could just get some honest advice... And to the other guy, you named about 50 gazillion things wrong w the car? If I'm going to check all that then I'm going to be busy overhauling my engine and not driving my car...Would someone who knows what they are talking about please chime in?

The hissing sound has me leaning towards turbo issue or vaccuum leak. Either of those would cause a lack of power. Did you accidently knock a hose loose while doing the plugs. I know you have to remove the OTE pipe and it's possible you bumped something that wasn't secured properly. Even with the DP install, something may have come loose. I would check all connections to the turbo and intake manifold to make sure that nothing came off, is loose, or cracked.<p>I would think with a fuel issue you would throw a CEL at least once, but I could be wrong. Also, a because the tune maximizes engine performance with boost pressure, A/F ratios, etc....it may be amplifying the problem as well. I don't think putting a tune on the car is a bad idea at all, it just may be making the problem that much worse right now.
