Re: [T3] Low power until the engine warms up


<x-flowed>You say you sometimes wind up running on just 2 cylinders.  Which cylinders 
do you lose?  Is it always the same pair?  You say a mechanic "repaired" 
some wiring between the trigger points and the ECU.  What did he do, splice 
some wires with crimped connections?  If they're not soldered (correctly) 
and insulated, those connections are "iffy" and can produce the intermittent 
problems you describe.

Look at the trigger points.  Make sure the little "room" inside the 
disrtibutor for the trigger points is clean.  Clean your trigger points by 
dragging a piece of paper through them.  Measure the resistance through the 
closed points.  Should be pretty low.

Look for any other bad grounds in the FI system. Especially the injector 
grounds, which can be problematic in 69s.

Cylinder head temp sensor should read 3k-4k ohm when cold.  When warmed up, 
resistance should drop to around 1k to 1.5k ohm.  Air temp sensor resistance 
should be around 400 to 500 ohm when cold and drop to around 150 ohm when 
warmed up.
