I have a 8 lb9 sat for probably 8-9 years looks like original injectors but probably replaced 10+ years ago and were not run.

PLugs connectors look and when hot they all ohmed exact;y at 17.4-17.6 seemed off they were all so close.

Just starting tuning and dataloggin I will run today so far it appears I have 140-160 BLM at idle I will see what drive it like but I know it bogs at throttle and no power


I checked plugs they look ok, black at bottom and brownish along arc with little white at tip

 

Anything 15 to 17 is healthy electrical wise. Try some Seafoam injector cleaner, wonderful stuff. Sometimes you can get a 2 pack for $13 at walmart or Napa. OHM test wont show if they are clogged or gunked.

I just put a fresh set of Bosch III's in the Camaro, what a difference. Had 3 out of 8 ohming below 12, one was dead, .004 .... smooth like a caddy now.

 

Yes I figure they might be clogged the fuel pump and tank were so bad the mechanic said he back flush replace most of the lines and all new tank and up
Pump. Was hard and orange the old gas

So maybe they are shot and explain lean condition

Also I notice after running up to temp I am seeing fluid leak on floor but it looks and smells almost clear not gas or tranny

And it is not under rapidly but by back of engine or under tranny and sems like water since it puddles far away it is begone my car not I. Front

Is this a rear intake manifold coolant leak

Or head gasket leak?
