I am sure someone can burn your chip to disable the injectors from firing,

The TCC lockup is very important to MPGs and performance, otherwise, the torque converter will not fully lock, meaning there is always lost power in the transmission.

Funny, wish I could find the picture.. someone blocked off the throttle body, cut a hole in the top of the plenum and bolted a carb on to their TPI car...

when instaling carb on an 85 vette does the ecm still control the guages and transmision was told the 85 did not have a lockout but dont know about the digital guages is there a kit that converts the system

If it's excessive, you should check the EVAP lines / charcoal canister for blockage.

Where is the fuse ( if there is one )?

replaced it with a 20 amp and it still blew. Anyone know what the correct amperage is?

postalvette wrote: you probably mean the throttle body. There's five bolts on each side connecting the intake and then the throttle cables on the front.

Can the ECM cause the fan to run constant?

The issue seems to be the knurl diameter. According to most GM numbers it "should be" a .509. After removing stock studs what I'm seeing on a used stud is approx. .497-.505. I'm guessing with compression of the knurl it will lose .005-.007 dia. The original hole size with spline is difficult to determine it "looks like".492-.497 but definetly not .500 ? (length is easy am going to use 2 1/4")

Why do you think GM decided to stop using those holes? Without the CSI, did they discover a better path thru the more open plenum-to-runner-inlet?

89Vette wrote:And, why change the plenum casting w/o changing the base casting? Seems like there's more to the story.

If the IAC air goes thru the plenum and out those small runner holes, how does it get into/thru the TB on 89-91 plenums

89Vette wrote:O.K., So what comes out of the small holes in the base runner tubes? (Qualify if different on CSI vs non-CSI units).

89Vette wrote:
I had thought they were intake ports for IAC-fed air. And, that the air made it's way down to the small holes in the floor of the base (small holes located in each runner).

it was stated that EGR gases are forced up/out thru those holes. And, that the "blocks" commonly removed for porting were put there to aid in mixing.

Would the ground problem be circuit specific to the cooling fan? I don't know where to start to find a ground problem
