Hey guys. I have an '09 SS/TC. About a month ago i changed out my tranny fluid with the recommended stock fluid from GM ( I had about 71,000 miles when i did this). Well, I dont know if this is causing my problem but it has to be something.
The problem= when im driving, the car feels as though it is hesitating. Almost like its "skipping a beat" per say. I do not think it is misfires, as it feels like something is just not catching, like the clutch or tranny. Now, i had a couple CEL's which i am in the process of fixing. I had a blown MAF, which i replaced, and i have a cam positioner sensor which i have ordered and am waiting to install. Could this sensor be causing this feeling of hesitation while driving? Its starting to scare me, as i do not want to get stranded or eat my transmission alive.
Any help would be appreciated. And if i wasnt clear on how the symptoms are. I can be driving steady at 40 mph in 3rd or 4th gear and the car will start slightly hesitating ( not really start bucking harshly, but just slightly back and forth momentarily). I'm praying i didnt "F" up by changing out this fluid in my tranny.
Thanks guys.

put that new sensor in and then see.

 

vids would be helpful..

 

Honestly it sounds as if the car is misfiring, do a comp test and leak down. Also look into getting logged with hptuners so you can check misfire vs cylinders and etc

 

it is honestly so subtle that you probably wouldnt even be able to tell from the video. and thats not just me being lazy, i have no problems taking a vid when i get off work. But there are no rpm jumps or boost/vac jumps.

 

thank you for your advice. I've seen your comments and know you are a knowleadgable person on this forum. I will be replacing the cam sensor tomorrow, in the mean time, after work i am going to have a friend scan the car for what is popping up on my cel. I would assume the maf code is no longer coming up, but i did have a misfire on cylinder one when he last scanned it. I am going to read the thread about compression test and leak down test and perform them at my first availibe time.
Thanks guys.

 

Do you have a wideband? If so does the reading bounce when it's doing this?

 

I no haz wideband :////

 

alright so i talked to my mechanic friend(s) and they said tonight, what will do is switch around the coils from 2 different cylinders. then spark plugs, then if need be fuel injectors. He said we can go from there with a compression and leak down test after that. so hopefully we'll figure out this problem tonight.
This car is so weird! today on my drive to work, it was about 90% fine!! barely any hesitations, then i got off the interstate and it started back up. but we shall see.
Thanks guys.

 

wow guys...so my problem wasn't such a horrible thing after all. We finally had time to pull plugs and look around under there. First plug we pull, the little white peice above the electrode came loose, so it was falling and covering both the electrode and the iridium tip (or if those are the same thing, it was covering where the spark occurs lol. and not the ceramic peice above the threads, but right below it. haha put a new set in gapped at .033 and boom. Thing ran perfectly smooth. Glad it wasnt anything serious cuz i have no time for down time. Thanks a bunch guys!
