The added time is to synchronize the timing of the injectors.. That is normal

Cut to the chase and replace the injectors too when you change filter.

An option that's served me well: Accel 150821 x2
Go to Autozone.com, add two to cart & select ship to home, input current discount code (SEE20 on 24 Jan 18). Shipped to your house <$510.

Go to jerrysgaskets.com & get plenum gaskets.

In your case, I'd look in starter valley for another rodent brothel. Be prepared to check all things for rat-snacking. Also, check vacuum condition.

I believe oil pressure must reach a certain level as well. But, yes all very normal.

If injectors are original I agree, replace them now.

I just checked the 150821 on auozone and it claims that the won't fit my car, is this correct or is the website confused. I have the car selected as a 1990 ZR-1 for reference.


Thanks for all the help so far!

Ignore the website, it is the correct injector. Here’s the best instructions from Marc Haibecks site....
