Default Codes pulled

I pulled these codes on my 89 z24i.
23-Idle Switch
34-Knock Sensor
41-IAT Sensor(Intake Air Temp Sensor)
45- Injector Leak

First thing in the morning, it starts up fine. Drive around for a while all is good, no hesitation, plenty of power. Turn the truck off for a while, when restarting I have to mash down the gas pedal to start it. Once started, no issues. Debating if I should just buy the TB gasket kit with the fuel injector o-rings or just replace the injectors. I need to replace a lot of vacuum hoses that are rotted. Any thoughts on the other codes for repairs?

replace the vacuum hoses first.....then see if you need to go farther. Hoses cured a bunch of ills on mine.

Also try unplugging all the sensors and cleaning the contacts on both ends of the plugs. Be gentle....that plastic will be stubborn.

Since you have lots of codes, I say read this sticky first:

FIX: erratic idle, low speed driveability, possibly more

Any plastic covers, parts, situations, or plastic dreams under the hood of an 80's D21 are going to be fragile and brittle. If you got exposed to extreme heat and cold for thirty years and were made of plastic, you'd be in delicate shape, too.

Working with anything plastic under the hood of an older D21 is surgery for sure. Call in the doctor and be gentle.

So far, one of the fuel injectors is bad, ordered one online should be here in a couple of days. Update soon.

I ordered a new fuel injector from two separate places online, both said they were in stock... called a few days later to find out that they are not in stock. Finding a fuel injector for my HB is alot more difficult than I thought it would be. Anyone have a fuel injector for my 89 2.4l they want to sell me?

Go with aftermarket, rebuilt injectors.

Original injectors can have hard and brittle rubber seals. They could be 20 years old.

Rebuilt or aftermarket injectors are usually made with something that can tolerate ethanol, too.
