hi i just recently got the car and when it hasnt ran in about 4-5 hour period its hard to start.it will start but miss and sputter and sometimes die also it doesnt want to shift out of first gear (auto tranny) but after about 4-5 mins its all good drives like a champ and i can start it with no problem after it has been running.

 

What maintenance has been done? is it more of a spark misfire or a fuel cut off feeling

 

the only thing I've done was change the oil and replaced the harmonic balancer.not sure how it feels?
