| In the past few weeks, the car has started to have cold start and idle issues. I really have to crank and crank to get it to start. Then it studders and backfires a bit. Once the car is warm, it starts fine and seems to idle ok. I replaced the fuel pressure regulator and that didn't seem to help. Next, I pulled the hose off of the IACV and sprayed WD40 in it. Since the car has been started today, I am not sure if that will help. The thruttle bodies have been cleaned in the past year... I did notice that the car now idles @ 1050 unless the AC is activated, where is drops to about 1000. Once the car was started today, I sat and let it warm up. Now when I hit the thruttle, it studders, backfires once and then revs up. When it returns to idel, it sits @ 1050. Any ideas would be greatly appreciated.
