I have a 98 intredid 2.7. The problem I have is after the car sits for 15-30 minutes and the weather is about 55 deg outside. When I start the car it often is difficult to start and has no power and runs rough. It feels like it is flooded. It will sometimes stall and after 10-20 seconds it runs well and then acts normal. I only happens when the temp is about 55. Never in the winter or summer. I brought the car in 3 times and no fault codes are stored. It is very difficult to repeat the problem. if the car sit over an hour it is O.K. or if left less than 15 Min its O.K.
