alright i just fixed my brakes today and everything was fine up until i stared my car again an hour later. THe strange thing is, is that its puttering. like a lawnmower... and when i try and accelerate it putts even more but faster, and it feels like the engine is trying really hard or something. i had put ngk platinums in at around 60000mi and im at 118K... does anyone think that the plugs could be the problem

 

did you checked the sparkplug cables one of them could be loose...

 

If you have pressure washed or just washed your motor, have a look at those spark plugs tube and check for water in there, or open your distributor cap, you may find some slight water deposited in there, i've done that many times.

 

It always one of three things, fuel spark or air, you ogtta narrow it down, you shouldnt have idle probs after a break change. Try pullin the plugs out and turning it over to see if it makes noise, then put the plugs in the wires and see if they all spark when you turn it over , check to see if your even gettin fuel w/ a fuel pressure gauge.
My car did this before and it was a combination of timing and fuel map
