Buckling/surge

[BOSS]

Hi All,

I have 2006 XLR-V with less than 3000 miles.

If I am driving the car normally at 40 mph with RPM below 2000 and want to speed up the car buckles and the surges and than speeds up.
If same as above but push gas pedal with more force than there is no
buckling. But I do not always need to speed up that much.

Is there a problem?

Possibly, the boost valve is sticking????

I would bring it in for service. Bucking & Surging is not good for the engine.

Do you have any aftermarket parts? Last time I saw that concern, the MAF was gummed up from excessive oiling on a K&N filter.

The vehicle is all stock except for Mild to Wild remote muffler switch.

Any advice is appreciated.

Well with less than 3k miles, I wouldn't think there to be too much going on with it. Unfortunatley you will just have to take it in. I can only speculate as to what the problem could be.

i had a 2002 DTS as my last cadillac. do they still have asskicking warranty service, or has anything changed? i was very satisfied with the brand and its dealers when i owned the DTS and before that my 91 60-special fleetwood.

now that my sl 500 is starting to annoy me with glitchiness, i'm looking at leasing or buying an off-lease or new '08 at the end of this year or in '09, but i do not want to have a bad and expensive experience. a bimmer, though not as engaging to look at, is another alternative, as is the much cheaper (in every way) vette, which i've not been super-excited about, stylewise. i'm pretty close to cured of my love of mercedes benz cars, and not very happy about it. thought i'd be keeping this one until it became a classic (it's a 2002 SL 500 "silver arrow", a very, very beautiful car). oh well.

the xlr-v, then, i hope will be a keeper.

Cadillac service is great. My dealer is excellent so is the service.
The car is really well made and put together. I probably have some
minor computer reflashing problem.

So nothing annoying or bothersome.

Highly recommend the brand.

I found 2 bulletins that may be related to your concern.

The first is an ECM reprogram, and the second is for fuel inj clogging that can cause inter. concerns.

Have them check/install the latest ECM software, and then run an AFIT test. If that fails have them apply the GM UPPER ENGINE AND FUEL INJECTOR CLEANER. Both should be covered under warranty. If they try to sell you the fuel inj service, that does not apply to the concerns noted, and have them reference current "Bulletins"

hope this helps

D3Mark,

Thanks a lot of the Bulletins. I will have them look that up.
Again thanks.
