Re: 89 S10 4.3 Need help troubleshooting TBI/IAC Idle issue
If it has a bad injector you only have to take out the bad one, but you need to look at the aluminum casting very closely.
When you install injectors without lube on the o-rings it can crack the TBI housing. Injectors are $4 each at the local U=Pull-It where I live. If the problem comes and goes it is more likely an injector, then a crack, but look to see if you can see a crack before spending money on an injector.
