i have an 89 firebird i do not have a reader but it only throws a code once in a while. but it has new idle air control sensor ,new throttle positioning sensor, new o2 senser, new maf sensor, has new fuel filter, recent coolant change, new radaitor hoses, new gold distrubutor cap and rotor, new wires, new spark plugs, new air filter, recent oil and filter change ,newer altanator, soon to be new fuel pump tanks droped right now. i think i got that all in it has a miss at idle and it will eventully miss until it stalls but it dont seem to miss when im driving it seems to have power takes off good but i have to keep rpms up at a stoplight or it will stall out can you please help its draining the bank throwing alot of money into it

 

But what codes is it throwing when it does?
Have you done any basic tests like fuel pressure , vac leaks , etc
Why did you replace all those part before 1st determining what your actual problem is ?

 

idk im getting a reader in the next few days but i belive its just the o2 sensor it only when i get down on it it runs rich. i got a one vaccum leak that im fixing but all needs to be changed. and idk thought i would eventully hit and miss but i have justt missed a few more detail is runs better when cold worse when hot

 

you don't need a code reader and if you are getting an OBD2 reader then it can't read the codes from your OBD1 car

you need a very expensive code reader which can be purchased at WalMart, Staples, Office Depot, Dollar Tree etc. The last time I bought those code readers it was for qty 100 and it cost $1

here's a link to the more expensive code reader but you don't need to get non-skid

ps- there are many threads and sticky's on how to read codes

I've provided a link on where to get the tool
