: POST SANDY: No Boost, Car Bucking

Took the V for a drive for the first time today- since Hurricane Sandy hit us. Any time I put my foot into the gas (which would put me in boost) the car would buck/shake and not make any boost. Oddly- no check engine light, and if I drove it smoothly & slowly you would never know there was a problem- it idled fine.

Parked it at the gym, and on my way home it was doing it again but not quite as bad. A bit more driving and it smoothed out and now drives fine. What could it have been? I'm assuming it was moisture related as the only thing different was it sat outside during heavy rain-fall and wind. Unfortunately our garage isn't finished being built yet. :crybaby:

Any ideas?! Thanks in advance everyone!

Maybe a little debris had blown into the mass air flow sensor and then came out? That's all I can think of.

Water in fuel?

Soggy air filter?

Did the car take on any flood water at all? I'm definitely siding with the "water got into the intake tract" theory. Just curious.

Hey guys- first of all thanks for taking the time to even speculate what happened. Figures- "I" end up with the odd-ball un-diagnosable issue. lol To answer your questions- I didn't drive it at all when it was raining and/or through any puddles. Thankfully where I am (South Jersey) didn't flood at all.

It has just over 800 miles on the odo and the only mod I have done (other than Eibachs) is a AirRaid intake. The only other time I experienced anything that felt like this was when I had a bad coil pack on a car years ago. Early in the mornings when it was moist and dewy out it would act like that. Btw, I just took it out for a ride again tonight just to confirm it isn't doing it again- and, thankfully, it didn't. I'll have to see how it fairs in the morning as there will be more moisture with the early dew and all.

Then again I could be barking up the wrong tree entirely- could just be coincidental. May not be moisture related at all. The fuel was low but not on E. Though- it was already driving normal again before I filled back up.

Regardless- loving this car to death, and looking forward to the rain-date for the local Caddy Meet & Greet at Englishtown!

I'd take it to the dealer and have them Tech-II the vehicle.

Just because there is no CEL does not mean the vehicle doesn't have DTC's.

I'm going to go with an iced MAF sensor......

Yeah, either a MAF issue or perhaps belt slip under WOT.

I had the same issue on my truck. I had a K&N kit on it. When it got below freezing the MAF would freeze up and cause the truck to go into limp mode. The extra moisture in the air probably doesn't help. Not sure if this was your problem but just sharing my past experience.

Is the Airraid tube clamped down correctly? It hasn't come partially off, has it?

It appeared to be all sealed up. I'll take the lid off and check the intake side. Today, on the other hand I was greeted by a "low oil message" at start-up. Was about a qt low. Only 900 miles on her so far. Wonder if the "low factory fluids on Vs" includes oil. Time to read through ALL the pages of the sticky!

Yes please check the oil levels regularly! Some have had bad experiences with oil disappearing. Count your blessings that you actually got a DIC warning. As far as the bucking, its likely to do with the intake system. Mine did a bucking/hesitation this morning under mild acceleration in 39* weather. This was right before it got warm and into operating temps. After that, it was fine...probably the MAF being finicky.

This doesn't necessarily mean this car is going to burn oil does it? I hope not!

^^^ Back in 09, a few V2 owners were losing oil due to leaks, and/or, factory fill goofs, etc. In my case it was a defective pan gasket causing my oil to disappear. Fixed under warranty - no probs since.

Same with me. Replacement gasket fixed it.

Mine is a '12. So here's hoping that it was a quirk from the factory (i.e. not enough fluid). Thank you everyone.

My first thought is a slipping belt

I'm going to go with an iced MAF sensor......I had those issues with my old SHO and its MAF way back. Dry and fine. If it doesn't come back anytime soon, I'd forget about it...
