Photo reminds me that I recently fixed my hood light from falling out all the time. About 10 layers of masking tape on one end of clear lens and now it holds in very nicely. I think a lot of owner...
There are only 2 wires for the door switches. One is grounded when both doors are locked and floats when unlocked. The other wire is grounded when both doors are unlocked and floats when locked. ...
Agree. The GM module gives you better dwell (less power consumed at idle) and current limiting (6 amps max) but still can run OEM unit with about 1.5 ohm coil.
Yes. Don't keep running it like that with a 0.40 ohm primary coil.
The white/yellow goes to the coil. The white wire gets 12 volts with the key on (from AUX relay). So you would connect the white wire to the white/yellow wire and tape off (or remove) all other...
The ignition coils normally need about 6 amps of current when running. The use of a resistor was the normal design so when cranking a cold engine you could get that 6 amps when the battery voltage...
I would think where the sheet does sharp bends it could thin that much.
Look at this thread. Start at Post #85 if you don't want to read the whole thing.

Thanks. Stopped in Harbor Freight and they don't have much for 3/4" drive unless you what to buy a full set. I just picked up a 3/4" to 1/2" adapter and a 32 mm 1/2" drive impact socket. You would...
What socket size it the outer drive shaft hub (the one that requires 270 ft/lbs). I need to have that socket and an extension for my 3/4 torque wrench on hand.
Does your car hold the idle at 775 RPM? The idle ECU opens the idle motor at power on so that should provide enough throttle to start without using the gas pedal.
The warm up regulator makes the...
Hard to see in that photo but I think I see uneven spacing which has shown the springs are a problem.
With all those symptoms, my guess is you have leaking deceleration springs. Did you look at springs?
Here is a photo of bad springs.
I used locktite to lock that holding washer in but as long as the correct O-ring is installed it should make a good seal. I also put some grease on the copper pipe which may also help with sealing.
It's best to compare vent temps not using re-circulation (max). With max air you can get very cold running a long time in the shade. With outside air it's a more stable test of how well the system...
I've designed the electronics in the dome unit to work with the Super Bright LEDs with switching regulators. I've tested with the switching LEDs in both dome lights and elsewhere (hood). Still...
Stock idle ECU always tries to hold 775 RPM. Does not matter hot or cold, idle switch on or off.
The idle switch just helps the stock idle ECU control timing when you release throttle quickly. ...
As I suspected, the CAT would not blow out on it's own.
You had a 50/50 chance of putting the sealer on the other side.
I think you get that with or without a CAT. Our engines run very rich when cold.
I agree. My CAT is hollow and I don't think it smells.
Yes that is the two pin connector that feeds the diagnostic port.
Glad you got it working. Testing with a meter does not always show the problem. Your 4 ohms with the meter is probably worse when the one amp of CSV current is flowing through that connection.
That proves your meter is working reading the correct value.
You normal readings should be swinging around 35 to 45 degrees on the 4 cylinder scale. So your 65 reading is telling you it needs to...
