Engine Performance problem
1997 Cadillac Deville V8 Two Wheel Drive Automatic
engine will idel most the time at 625 to 750 rpm without stalling. When put in drive with brake on will stall 75% of the time within 5 min some times just a near stall. No pcm codes. Iac, tp, egr, emc, map. Maf have all been repalce. Pcv has been cleaned, throtle bode has been cleaned. 2 of 4 o2 sencers replaced, vacume holdes stedy at about 15, fuel presure holdes stedy at 40 lbs. Dos not stall well driving. Getting worse afrad to go on planed trip. Whats wrong? Also if pcm is replaced dose it have to be flashed after instalation or can it be done at a deler then instaled?
have the same problem?
