Tahoe 2010 with CAI & Magnaflow Help !!!

[tahoe2010]

Hi ,

my Truck is Tahoe 2010 5.3

i install magnaflow exhaust 10 days ago ( amazing )

and every thing is ok

yesterday i install Volant CAI after that i run the car for test

its awesome sound but i feel like i had some problem with RPM when
the car on idle ,,, little up and down (not stable ) specially when i am stop after run the car.

Then ---- Today

after i go to round trip about 30 mile when i stop the car shut off

i restart the car and run again when i stop the car ,,,, the car shutoff again

and i feel like there is something not stable on my engine ( little vibrate ) and the RPM going down about 300rpm

So, What should i check ??

Thanks in advance
Bob

make sure that the cold air intake is plugged in correctly, and also tightened down. other than that i really dont know.

Folks with 09+ running Volants have had issues running rich. Some have stated that they were told to use an O-ring for the MAF, that was enclosed in the packaging but not addressed in the instructions. Did you install that?

Mass air sensor maybe?

No Sir ,
there is no O ring .

[JennaBear]

I would definitely give them a call. We have had a lot of customers who have had issues with these intakes, it is a matter of the intake forcing the MAF to read wrong.

Keep update

I have an 09 5.3L. After installing the Volant CAI, about a week later the check engine light came on. I never had any idling problems though. I unplugged the battery for an hour, although some said 20 min should do it. Reconnected started up and no CEL now. I ran a OBD2 code reader and there were no codes pending or present. When the CEL was lit up, Onstar said that the problem was with the "engine fuel control system" I am thinking that unplugging the battery helped reset the computer. It is likely that the computer is still learning from the MAF and maybe the light could go back on. Haven't got that far yet though.

^ How does the exhaust directly relate to the MAF?

??

[dmerk1978]

i'm not sure either, all i know is that a 2009 should not fit a 2010, unless custom fitted by the installer, i'm unware of any exhaust being to market on 2010 unless custom made or r&d from the manufacturers. just my 2 cents

[Zed 71]

IMO the 2009 should fit 2010. I am not aware of any changes that would affect exhaust fittment. However, the CAI for 2009+ are definitely not compatible with previous years because the MAF housing is different.

My previous post was regarding mad's where he indicated the exhaust was not compatible because of the MAF. There is no direct correlation between the exhaust and MAF fitment wise.

If the battery cable is not unplugged or the o-ring is not swapped out your kit will through a check light did you get the problem fixed?

there is no check engine light pop up
also i double check the MAF plug is OK and i reset the battery

but still have a same problem on idle RPM

[mtbennett24]

Can you explain the o-ring? Are you referencing the seal that attached to the end of the tube then to the motor?

No that is the throttle body grommet, When you remove your sensor on the 09-10 there is a red rubber ring that seals the sensor to the tube this gets replaced with the volant one

[mtbennett24]

There doesn't seem to be any mention of this o-ring in the instructions that shipped with the cai.

PM sent regarding how to get one.

Volant1 is on the case now, but it is definatley a MAF issue. I am surprised a reset did not fix it. Are you sure that the MAF was not damaged when it was taken off and reinstalled?? Just checking because if that little sensor in there got damaged that would most certianly cause the problem you speak of. Rather surprised that there is no CEL though.

i'm sure the MAF is perfect and the wire is ok

[tahoe2010]

i think the problem com from powercore filter

[JennaBear]

Nope, that is not the problem either.

[tahoe2010]

Nope, that is not the problem either.

Check that sound (Tuner)
nah, that's fine then...

I checked the instructions before too... yours doesn't have it...

it must have that new "power core" filter... the one that looks like a bunch of plastic straws stuck together lol...

have seen others with that new power core filter have the similar issue like you... but they're ltft's weren't THAT low... they were only down to like -14...

so, you are probably fine judging by others I've seen and that powercore filter track record...

[JennaBear]

Huh?

[vinnyray]

Did you get this figured out? Any updates on the cause?
