Slight Idle Bump I have a stock 2000 TA with basic bolt ons. When my car idles it has a slight bump every few seconds. I was wondering where I should start looking are why it is doing that? I will try and record it and post to see what you guys think.

I have also noticed that my idle doesnt come down quickly qhen i push in the clutch it actually ramps up to 1100-1700 depending on how fast i am going. them slowing comes back down to normal of about 800rpm. I did just replace my coolant sensor. This may be a completly different issue, but it just started happening and I didn't think to post it before. Also my check engine light comes on occasionaly.

I have the same problem. Its like a slight miss, with no check engine like. I put it on misfire counter, and it picks up nothing... Every few seconds, I feel it through the chassis... new plugs and wires. I havnt figured it out yet.

I have HPTuner and tried to log some info on it but it doesn't show up my normal logging parameters, cyl air mass, air/fuel, maf, map, etc.... Maybe i'm not looking at the right ones, man its getting to be a bitch this one just has me fooled for now. lol

I also get a noisey lifter every once in a while. With that, i figure that might be causing it as well. Otherwise I dont worry about it to much. it does run really good other than that. Hopefully this winter ill get a cam, then I REALLY wont notice a slight bump in the motor.

Its definetly a miss. Its been getting worse and now is starting to backfire sometimes. I did the !AIR and !EGR and put breathers on the valves and a catch can where the EGR was. Is there something wrong with the EGR somehow? Or could the fuel pump or regulator have gone bad? I am getting a P0300 code so it is not just one cylinder.
