Bad idle when cold
My car is 2002 Vert all stock no mods, It appears that when its cold it idles rough, replaced plugs, replaced front o2 sensors, cleaned MAF, checked for leaking vacuum lines, and now today replaced the fuel filter I only use Chevron 93 and occasional I use a injector cleaner (Techron or Sea foam), Still same problem there is no codes either,, I'm trying to avoid the stealership, looking like I'm not having any luck, does anyone think that it might be a weak fuel pump... Thanks guys
