So I was coming home from ice skating with the gf. And I here this pop noise at idle it does it about every 4 to 5 secs. So I was almost out of gas. I put high-test gas in the car thinking ok maybe some bad gas or condensations well that didn�t fix it. So I am sitting at the light at the cars running rough around 1000 rpm�s so I bring it to 1200 I take my foot off the gas and it falls to 450 now I have a vacuum gauge in my car and it didn�t move it took its normal reading at idle around 21 20 so I am pretty sure there�s no vac leak. so yesterday I took all the plugs out. They all look fine not showing any sighs of running to rich to lean. All the wires look fine not cracks or white spots and to top it off there�s no CEL. So I am stumped any one got any ideas.
