i just converted my car to obd1 and swapped a 92 ls in it ,,,, we got everythign done and when i drive it seems like it wnats to bogg downa nd die on me and at idle it does the same it will go to down to like 200 rpm's and and sometimes cut off , today i just looked at my alternator belt and it wasnt on there , but it was on there when we where doin the timing and all that stuff , could this prob be relative to the alternator maybe ?
