sluggish and hesitates???

Car just seems to do this on cold start up and drive. Do camaros need time to warm up?? Feels like thiers a hesitation in acceleration in low gears. Tech says cant find anything wrong.

There's a thread a few days old on here discussing the surging when the engine is cold. Seems to be the norm until it's warmed up.

You could do a fuse pull to see if it makes any difference

So you just fire her up and start romping on it? Give the car a little break. What do you expect?

It's normal, all cars have this "feature" more or less, especially small displacement FI engines but also larger NA engines.

Mine does that, even with all the mods I have... It'll feel like it gets a small acceleration surge while cold and rowing through gears, other times there's a delay in the pedal and the engine response.. It's all gone once the engine is at operating temp..

I just write it off as making an engine do work before it's at operating temperature.. The manual trans and my suspension make the sensation very exaggerated.

However, if you feel something is truly wrong with the car and you feel the mechanic may have missed something.. bring it somewhere else.

I've never noticed any hesitation during cold starts and mine has sat outside in sub-freezing temps. Is this specific to the V8s?
Just curious.

If it clears up once you get to working temps I would not worry about it.

I know my car vibrates like crazy for the first 2-3 miles when I drive it out of the garage after sitting at least overnight. Nothing but the tires getting back into round again!!! Worried me at first until I realized what it was.

Got worse when I put the 275 on front and 315s on back but goes away quickly and reminds me to let things settle in when starting out on the road with the camaro.

If it does not get better at working temps, something is clearly wrong.

Before I bought my Camaro I test drove an RX-8. Took it out one day in December and punched it hard and the engine just died. I was worried I had damaged it. Seems that the red line on an RX-8 moves. When it is cold it is lower than after it warms up, and yes the tach did display a moving red line. Sorry don't remember the numbers, but both ridiculously high because it is a rotary. 8000, 10000 perhaps?

If you changed the tires and the shake is still there, it might not be your tires.

It's always been a habit, cold weather or hot, to let mine idle 3-5 minutes (longer in winter).

Don't know why I do, technically speaking, I just do.

Mine is slugggish in the morning so I don't force the issue with the throttle but later when I come home, very little sluggishness due to warmer temps. I just take it as part of letting the car warm up.

All of our cars do it. Here in the Northwest it doesn't get that cold, but occasionally it will dip into the 20's. There's a steep hill about 1/4 mile from my house, and when pulling out and heading up the hill, you can definitely tell, esp in the Camaro, that it's dumping fuel and not making much power from a bone-cold engine. The Jeep and the Audi do the same thing.

Your car is fine. The LS3 does this because the computer is not communicating with certain sensors (O2, etc.) when the car is cold. Everything has to be at temperature before the car will run as intended. There's nothing to find wrong, it's how the car is designed to operate.

Mine is doing the same thing. It's very annoying most of it goes away when the temp warms up but some/little still remains. I wish someone knew of a way to fix this

Have tried taking the vehicle to the dealership for a proper diagnosis? Please let us know if this is an available option for you!

The dealership told me since there is no check engine light then the car is fine.

I know GM is well aware of this issue its nothing new. I wish GM would address it and explain it and come out with some type of fix.

If you could please send me your first and last name, address, phone number, VIN, mileage and involved dealership, I can do some more research regarding the issue you are experiencing.

I look forward to your correspondence.
