No check engine light, It is hard to start some mornings but very rarely. I have always replaced all filters on time. No smoke ever, it always restarts but sometimes stumbles and stalls again several times before it returns to normal, It is very intermittent. Also trans temp gauge pegs out after about 2-3 miles of driving from cold start. It is running mid range in the gauge and then in just a snap it pegs out. Could this indicate a possible connector/wiring problem at the PCM?
