im getting heitation between 2000-3000 rpm, it hunts for an idle, when warm it idles at nearly 100 rpm , takes about a while for hesitation to go away, once it gets cold again the hesitation comes back... heres some things ive tried to fix the problem: tried new MAF, cleaned and adjusted TPS, used throattle body cleaner through my IAC and the rest of my tubing, used seafoam, put a new PCV valve in, cleaned connecters to my fuel pump, put in new 02 sensors, and worst of all, i cant get a CEL to come on so i have no basis of what to look at.... if anyone could give me a good answer to my problems that would be awsome
