Bucking/Stuttering

[Trotter715]

Sometimes when I hit my brakes and than go to accelerate in the same gear quickly, there is a bucking/stuttering that occurs. It does not increase speed smoothly. I had this problem and a buddy suggested changing the spark plugs,which i did and it went away for a little bit but now it is back and occurring more often. Anyone know what the hell this is or could be??

I think I have the same problem..
Im not sure, but I think it may be motor/trans mounts

Clean ur MAF first. That doesn't help pull oyur engine cover off and check ur vaccum hoses.

No way is it the mounts. I too am having this problem. I've had my NGK R spark plugs on my 30V for about 10K miles which seems too short of a time for them to die out.

Let me just add - On Trotter's car, the spark plugs are something along the lines of Autolite (cheap autozone spark plugs) but he has only had them for like 300 miles.

Also, on my car, this happened after I seafoamed and after I put regular gas in my car. That said, I noticed my vacuum lines were really shitty and cracked and what not. And I cleaned my MAF a while ago but not long enough where its dirty-ness is enough to affect the engine since the car went 120xxx miles with it never being cleaned.

I also had this problem last year so I got the spark plugs and it went away til now. So I'm thinking that it's the spark plugs again or spark plug wires.

Sounds like a common misfiring issue with a common solution. Ignition coil or spark plug.
