i am recently having trouble with my 89 iroc it has a 350 and it ran perfect since it had a rebuilt motor with aproximately 15000 miles. but since i did not use it sat in my garage for about 6 months and i would ocasionaly turn it on. i decided to start using it again so i took it to get the smog check and it past parfectly. i used it for a bout 3 weeks and i began to have problems. i would drive it fine but all of a sudden it began to stall so i put it i on neutral and began to give it gas and then put it back on drive and it worked fine. the next day it would not turn on.

i replaced cap and roter, fuel pump, fuel pressure regulator and nothing happens, it just cranks, but if i spray carb cleaner on the throttle bidy it will start but then will shut off ones it burns the carb cleaner. DONT KNOW WHAT IT CAN BE PLEASE SOMEONE HELP ME!!
