1990 Fuel Injectors
Hello all,
I actually have a simular post on the discussion forum. I am going to replace my injctors on my 90 C4 with Boch III's. As simple as it looks, is there anything I should be aware of when replacing? Any special tool(s) other than regular mechanics tools? When new ones are installed, snug fit or a slight torque fit?
I am being as pro-active as possible before I begin.
Thanks all.
Tim

The job is 6 hrs of wrenchin', a few minutes of actual brain work, depending how many short cuts you know. the injectors are a push in fit. I did mine and had not one problem. Plenty of time to think ahead while removing and assembling screws and bolts.
better get a flexible magnet pickup tool! also, there is a method that does not require removing runners -which is half the friggin' job. on here somewhere.

I did that job a few weeks ago. I used the procedure without removing the runners. I found it on this forum. It had a list of tools. Not too bad of a job. The only thing I found a bit tricky was trying to bolt on the upper plenum to the runners which had all the lower bolt tight. The upper bolts did not want to line up with the holes in the upper plenum. I had to take care not to cross thread the bolts in the aluminum. I had to tap the plenum with a mallet as I inserted the bolts to get them to start threading properly. Anyway, the car runs really good now. Heater core is next!

I replaced mine following the Haynes manual. As great as the FSM is for data and info, it is not intended for the DIY'er. It is for the GM trained techs, as it says more than once.
