i am just curious....my 94 camaro(bone stock) has a slight studder when you barley step on the throttle. is this normal? or am i just being paranoid? Im thinking that it might be the map sensor? Or maybe the maf......but im not sure. Had the car for a month now.....done this from day one.....any ideas?

Welcome

Not normal. Start with a basic tune up that includes a stock or MSD Cap and rotor.

Check fuel pressure and grounds next. It would not hurt to have the injectors cleaned

starting to wonder if it might be a fuel problem? does it when its cold, does it when its hot, does it at any time...

Time to dig in. Check compression and leak down while you are at it. have fun with 2 and 4!

EGR issues are know to cause a low speed stumble. To try and help diagnose you could disconnect and plug the vacuum line to it and go for a short drive.

With stock manifolds it's more like #8.

I always just dropped the Y-pipe and then you could get 8 and 6 pretty easy but 2 and 4 were always bloody
