M50 Coil Stuff For Ross

Ross,

here ya go

[Ross]

Thanks Bob.
I can't find a spec for the connectors to the plug or the coil secondary.
I'm chasing an off idle stumble on a '95 M50.
It was throwing a code for the O2 sensor and I was reluctant to change it as the one in the car is recent. Checked the voltage, it never varied so I put a new one in. Perhaps better now but still there, response is crap if you snap the throttle open from idle.
Plugs are NGK bkr6ek ~ 18k on them, look fine. Coils all checked at .5 -.6 ohm. Connectors are all about 2.6k ohms. Plug holes are dry.
I'm convinced no vacuum leaks. ICV is clean. Throttle body is clean and opens smoothly.
Pipes look like it runs rich and fuel economy sucks.
Idle is worse after new O2 sensor.

Any ideas guys?

connection to the valve cover wher those two hoses hook up.

Sometimes the o ring dies and lets air in

Checked it and the one under the intake.
I'm beginning to think it's the injectors.

try a dose of Seafoam in the tank, or mega dose of techoline

I buttoned it back up and dummied the computer. Better but not right.
I'll give the injectors a listen tomorrow. The gas tank is near empty so a big dose of Techron and a good thrashing which it hasn't had in.... ?
If that doesn't work I'll send the injectors out for ultrasonic cleaning and flowing.
If that doesn't work I'm well insured.
