hi folks -trying to figure out a weird promblem with a kia 2.0 cust says it is just stalling when going down the street 30mph...it was starting back up but now just turns over ...getting spark....fuel ...and timing belt is good....weird thing is it will sometimes start if cranked long enough it kinda goes faster faster faster till it will run but that happens rarely...month ago it had full tune up wires plugs air and fuel filter oil change...now we are doing a water pump

so while the fronts off the motor iam asking for some advice....thanks crank.it
