i bought the car at 143000 miles. ran PERFECT, all the way till 175000 miles, and now having trouble. it has a hard time starting for the first time on a hot day, and 1 in 500 stop lights it just shuts off out of the blue. and starts right back up no prob. and from excelleration, at low engine speeds, it stumbles horribly. high engine speeds if fine. it started about 5000 miles after i installed a new excell coil. i replaced it with a streetfire coil. same exact thing as soon as i installed it.

basicly......
it stumbles at low engine speed,
it dies once in a blue moon at stop lights,
and has a hard time starting when its hot outside,
but starts good when its cold.

PLEASE HELP!!
