the history is 1yr ago it started acting up wont start or hard start also at any steady speed(cruise on and off) it would rev very high 5 to 6k my guess as no tach. it would do this at a complete stop also!!!good thing brakes are good. anyway i amm usually alone when i drive but 1 time i had a friend check for spark as i cranked and yes good spark so to make this short since then i have replaced:fuel filter, fuel pump,spyder assy(new),O2 sensor(what a bitch),a tps or close(small 1 mounted on top/side phelum)and a waste of money on a new dist assy i did all the work myself so know it was done right. any help?
