car is hard to start when cold and i must give it gas to start once started it idles up and down for maybe 3 secs until settling at a unusually high idle speed. Also it shifts through the gears more slowly than usuall during acceleration and if i come to an abrupt stop and try to take off immediately it takes a sec for it to switch back into 1st gear and i have to wait before i can move again but only after an abrupt stop. The only codes are 26 and 27 has had recent tune up except for fuel filter and recently changed ecm but kept orig prom. Please help!!
