my 3.4 94 grand prix has started upon a cold start up the routine of surging to around 3000 rpm then dropping off to stalling several times till warmed up or around 5 minutes or so, after it's warmed up or driven a couple of minutes.it's fine the rest of the day.i replaced the iac and it had no effect.i can't see where it would be a tps,it would act up all the time,there are no vaccum leaks,like i said it only surges and stalls first thing in morning after setting all night long. any ideas?? thanks
