Ok. Posted the KS values earlier

289k and 290k. Sounds like they're busted.

Ohmed the injectors all at 11.8 ohms each. Sounds like they're winners.

So.... what else should I do while I'm in there.

I have to pull the plenum to reach the KS, and here's my list so far:

- Cleaning the IAC- Radiator flush, and I have upper, lower, and new thermostat.- Cleaning the EGR- Cleaning the Throttle Body- Cleaning the plenum

Here's some thoughts:

- Replace the O2 sensors?- Should I send the injectors (since they ohm good) to deatsch works so I don't have to worry?- Valve covers? How do I know if the engine is leaking oil?- Spark plug replacement? I'm not sure if they're due... but the car is at 100k and I don't have the full list of stuff the previous owner did.

Also, I saw the list of parts that was posted on NICO. Are they applicable for the 94?

Looks like I'm going to blow through my 1500 budget to get this car all back into shape! =D

Oh... and PopPop still hang around? I noted that he's got some KS available?-

Measured at 2000 ohms? Then no. Check for cracks, etc.

Do not buy used unless you want to be under the plenum again soon.

Yes on VC gaskets and spark plugs because parts are cheap and labor is less now.

I'm confused...

Can someone explain what the VOM readings for the knock sensors?

Did you check my thread about the under plenum and all that I completed during that time?
