2013 v6 throttle body porting possible problems - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

'13Inferno · 11-17-2013, 01:11 AM

For those that haven't heard, I got my throttle body ported And had the time from hell right after. V6's don't handle it as well as v8's. I kept getting a check engine light, service stabilitrac, and engine power reduced while driving. Along with having my car actually stall while driving 70mph on the freeway. And when the engine power reduced comes on, the brake pedal becomes solid and can barely be pressed in, so hard stopping is non existent. After multiple attempts to reset the system by pulling the battery, I think we finally got the code to clear and stay off. Bodih helped me clear the code. Made it back home and the code hasn't come back on. Need to try driving again tomorrow to double check. Me and bodih checked my maf sensor and we think I have a weak one. Mine has only one letter "Q". I think with the injen long tube cold air intake and ported tb, the sensor isn't powerful enough to read the increased amount of airflow. So I might be ordering a new strong sensor so I can have piece of mind.

Anyone considering a port and polish on a new v6, talk to me first just so I can fill you in on a few things. It does make a world of difference power wise driving but could possibly cause an issue the first time. Thanks to joe cordes of Phoenix for the outstanding work, and everyone else who helped with my car today. It's much appreciated.

I was just going to order ported tb for my 14"3 LFX.

Did you get it ported, or do it yourself etc?

Never had a problem with my vmax one?

That is far from typical. You have some sort of serious issue going on. The V6s responds very well to the VMAX ported throttle bodies (better than the V8s) without any issues. You mentioned that you had your throttle body ported as opposed to ordering one. Who ported it?

Rhyno81 · 11-17-2013, 05:55 PM

sounds like the porting job was wrong? VMAX throttle body was perfect

Kessler · 11-17-2013, 06:45 PM

My VMax from Apex Chase running fine. No codes...

etmx183 · 11-17-2013, 07:23 PM

V-max no issues for over a year now. Make sure the blue O-ring is in the intake. I have solved several installs of running issues, won't idle, lack of power because the O-ring was left out.

I had it professionally ported from a performance race shop. There was 5 Camaros total that went yesterday and had it done. 3 v6's and 2 v8's. One of the other v6's had the exact same problem right after it was ported but they disconnected the battery, drained the system, and the computer re-learned everything and they haven't had any problems since. Mine for some reason, the computer will not relearn the increase in airflow. I keep getting a C.E.L. And reduced Engine power. The guy porting them said the v6's you have to disconnect the battery otherwise, it will throw a code and cause problems.

I went to a performance race shop, and they ported it.
If worse comes to worse, if I were to order a vmax ported throttle body from you, would I still be able to send this one in as the core charge and be refunded the $200?

Ya, I have removed the throttle body and reinstalled it a couple times already just to make sure it wasn't an install error, but everything is installed perfectly

I just drove it today and all the problems happened again today twice. I am going to borrow a friends 'strong' MAF sensor and see if the problems go away. I am thinking I might have a weak MAF sensor. I know there was a big problem with weak MAF sensors. Mine only has the letter "Q". Everyone I have talked too says a 1 letter sensor is weak. The strong sensors have more than 1 letter. And since I have an Injen Long Tube Cold Air Intake and the Ported Throttle Body, Maybe the sensor I have cant read the increase in airflow. I will try this out and let you guys know how it is later this week

I was going to try swapping with a friends maf sensor but his is entirely different. he ordered a strong maf sensor from your website. I was wondering if you sell a strong maf sensor that will fit my v6 lfx? my sensor is one of them that only has 1 letter, so I think mine is a weak sensor

We would not be able to take it as a core because it has been ported to unknown specs.

The V6s do not have the "weak" versus "strong" MAF sensor issue. It only applies to the V8s.

Joe@CPR.com · 11-18-2013, 01:28 PM

We are the shop who ported them, we have never had a single issue w/ any of them and these are the first 13 v6's that have come into the shop to get ported. Shouldn't make any difference what so ever and all the precautions were taken to ensure no issues from seeing what happens w/ the v6 cars when you remove the tb and don't disconnect the battery. The codes that are being thrown are typical to that of taking a normal ls car and turning it on w/ the tb disconnected. I simply instructed them to visit their local dealer, as they all live in Tucson and simply have the code deleted w/ a Tech II as TB codes are a hard fault code and no general scanner will delete it. These codes popped up long after they came to us and were on their way back home. If they were local to us we would simply use our Tech II to delete the codes. We have hundreds of these TB's out there with only hearing issues from people not disconnecting batteries on the v6 models. I have been in touch w/ the person who organized this TB porting day and rest assured whatever we can do to help we are on top of it!

FLYNNZL1 · 11-18-2013, 02:06 PM

Thank you Joe for responding. Just a FYI, none of the V8's from that day have issues. I hope the fix is a reset, one of our members reset his codes Saturday night back in Tucson, and the problem came back, Do you need a better tool to do a deeper reset?

Sikoriko · 11-18-2013, 02:19 PM

How about the plug? I have changed mine out no cable pull and no CEL's. could be a bent pin on the plug going to the TB?

I was one of the v6's that had it done. I have a convertible and drove home with the top down so if the "check-engine" light came on I didn't notice.

But this morning firediti up to go to work an sure enogh "check-engine" light was on. Drove to work w/o any performance issues. Is this okay to drive until I have the dealer (or someone) check it out?

thanks - Gus
