Q-Jet Block Off Plate
Unless installing a plate for appearance just leave stock one on and proceed with choke conversion. It is a tube preheated by the exhaust. Will not affect drivability in any way unless rotted out.- fast 99

Throttle sticking
If base idle isn't adjusted properly throttle plates can stick. In other words throttle is closed too much causing plates to stick in the bore. Disconnect throttle cable to isolate it from the TBI unit. Check if it still sticks.- fast 99

Emissions pipes
Yes, some vehicles had dual bed converters. Not sure if 87's had it. That was an odd emissions time frame with dual air pumps, carbs, some carbs with feedback and TBI. All dependent on GVW and motor option. A vacuum hose manufacturer delight.- fast 99

New engine installed - need TBI timing/idle help
Have seen that connector under the carpet or near firewall inside floor passenger side. If under hood it is separate and usually easy to find. Not sure of the year have also seen it behind the glove box.- fast 99

Header farts
Above is an absolute, recheck recheck recheck. Suggest applying a small bead of high temp silicone to both sides of the gasket, let it set up for 15-30 minutes, install. Just snug bolts up and come back the next day and tighten. Also, cheap headers usually do not have a thick enough flange...- fast 99

Brakes
Agree with the possible diagnosis. Question replacing the valve unless it has some other obvious issue. Read several posts about new PV's leaking or just plain failing. One failure was on a TV series, leaked. Most of the valves are offshore production.- fast 99

1987 454 TBI down on power, runs good otherwise
Plugged exhaust? Drive with a vacuum gauge shouldn't go much lower than 4 inches. Alternate method loosen the header pipe slightly. Low fuel pressure?- fast 99

What’s the solution to this?? Idle adjustor
Would be better to properly diagnose the problem. Really need to know the IAC counts. If you close the throttle plates to fix a cold start issue it could have a sticky throttle or die when warm. The IAC can only adjust so far then other undesirable things will happen. Some possible suspects are...- fast 99

Edelbrock accelerator pump
Put the old coil back in and does it have the strap ground? I know people are trying to improve their vehicle, but the quality of parts today is sometimes questionable. On top of that a stock HEI coil can usually produce twice the KV necessary for combustion.- fast 99

Pass power window
Assume the question is what's wrong? Need to check power at either the switch or motor whatever is easier first. Then proceed uphill or downhill to the problem. Been repeated here numerous times, new parts are suspect until proven otherwise. Lots of junk out there.- fast 99

No drill,no ream, DIY Quadrajet throttle bushings
Interesting, Re-bushing like it has always been done isn't hard but at the very least requires a reamer. Can see where that might be a good option for one-time rebuilders.- fast 99

Factory smoke
Hooking up a battery backwards can cause all sorts of electrical gremlins. Yes, it's possible damage was done to either the wiring or gauge itself.
