i have a 96 s-10 blazer 4x4 and it has 4 codes. p0102, p0103, p0171, p0300. 1st mass or volume air flow circuit low input, 2nd mass or volume air flow circuit high input,3rd system too lean (bank 1), random misfire detected. it has a starting problem, when u go to start it no matter what time or how long it has been sitting or anything it take many cranks to finally get it to start and when it does it is weak for 5 seconds or so then it goes to normal idle. ive been thinking it might be o2 sensors but ive been reading around on here and ive been thinking other wise. please help me asap i have to get it smogged for my reg.

 

use the search function and type "P0### explained" and enjoy
for example here is P0171 in all it's badness...

hell i'll do P0300 too since it's a fun one...
