highway skipping
Now that i have everything running good. Today i was on the hwy and i was crusing and it starting to studder as i accelerated. so when i got off hwy it did it less at slower speed. got home and checked the intakes. they are all on nice and tight. so does anyone have an idea what it could be. I cant figure it out.

I haven't been following what all is done to your car? Can I get the year and the mods you just did?
Thanks

exhaust, intake are the only mods. reciently i chaned out the battery, plugs and wires. it would almost die after rev or if i took out of gear on hwy. that cleared up on its own. 2 wks later i was on the hwy and if i gave it some gas to go up a hill it would gain and loose power. kind of like a skip or shutter. i looked up codes. the only codes that where current was the tire pressure sensor after i reset, check engine light went away but is still doing same thing. any help would help alot.
thanks

My best guess is a bad mass airflow sensor. O2 sensors are a possibility but doesn't sound like it here. My old C5 had the same problem. I changed everything that you did. Plugs, wires, coils and even installed some new O2 sensors. I would pull out and put the pedal down and it would just bog down on me or I would be out on the highway and it would do the same thing yours is. I ended up getting a MAS from Granatelli Motorsports and the problem went away instantly. They have a nice tuned MAS made especially for cold air intakes and it's only $250. I wasn't throwing codes either.
