poor performance
ok, I've got a bit of a studer in the engine when accelerating slowly from a stop. it doesn't happen every time and if i accelerate a little faster it doesn't happen either. i thought that it was trans trouble at first so i had the local trans shop do a fluid and filter change and check things over for me. said it look ok and that what I'm noticing is engine trouble that should be fixed with a good tuneup. he wanted over $350 for a tune up so of course I'm doing it myself. I wouldn't have anyone else do it anyhow! So, I've already cleaned the K&N, done the oil change, fuel system/injector cleaner... I am going to do Fuel filter, plugs and wires. Is there anything else that i can look at that might be the cause of this problem? it is just annoying more then anything.
Oh, i think that the plugs will probably fix it though. My dad and I tried something he read in a magazine of his and filed back the negative electrode on the plugs to expose 1/2 of the positive electrode... supposedly more horsepower, but i never noticed anything special for sure. I wonder if that "mod" is causing this problem now. either way, the plugs are about 2 years old i think so they're out!

I used to have this issue on the 99 SE in my sig.
It ended up being a combination of things. What I did to rectify it were:
Replaced fuel filter
New TR55 plugs
New Delco wires
Cleaned the throttle body
You'll probably net the most improvement from the throttle body cleaning.

In the past, I bought the TR55s from Advance or Murrays.
The TB cleaning can definitely be done in one day. I'll search and see if I can find a link of the procedure since I don't have time to type it all right now...
