Injectors are out

[Eagle]

All of them ohm'd out at 12.0-12.4 Plugs looked ok, some wires look a bit bent up at the injector plug but nothing nuts. Sure hope I dont have a bad wire to chase down. That'll SUCK.

chasin a bad wire would suck.....What size are those?

 

[Eagle]

Same injectors that are in Toms, 80s.

a bad wire isnt hard to chase down with a meter.

 

[Eagle]

yea, just need to find a diagram, take the bulk head connectors off the PCM, chase down the wires for each injector plug and ohm them out... problem is its intermittent and only between certain RPM. So I really hope/doubt its a wire issue.

by far the best tool I own. a power probe, not the open circuit tester.

fix that stumble to put more boost to it and C16
You gonna launch the car over 3k this year?

sorry you are having such trouble, im in the same bout too!

tho good news taht they werent the injectors, i got the same ones

I'm still betting it IS an injector. The car ran fine for months and suddenly developed this intermittent issue... ALL the ignition was replaced... so I know that's not it. What else is left?

AIR? I think not. I'm ramming a metric shit ton of air into it. It actually gets to be less of a problem with less boost.

SPARK? Nope, replaced EVERYTHING and tried working on gap too. No change. Took the 2 step out, no change.

FUEL? Fuel pressure stays constant when this occurs. I've swapped my primary and secondary pumps to see if that changed it. Nothing. Last thing is the injectors as far as I can tell.

Just sucks.

 

[Riski]

guess you can buy 4 maybe and swap each side out....

 

[Eagle]

Yea, just spend another $250 for some injectors that are like 6 months old to start with.

They should be replaced by the place I bought them for if they're bad already.

Issue was on B1 for sure too. I could see it in lean spikes from the narrow band O2 feedback.

I totally understand the frustration. You remember that my car didn't run well for two years because of an ignition problem. After spending $400, we figured it was either the dirty MAF, dirty filter, or coils. I imagine you've already checked all that nonsense.

If u want to bring that beast over tomorrow you can toss my injectors in and see if that's ur issue.
