When you cleaned out the idle valve did you use lots of lube, or parts cleaner? I ask because I always use parts cleaner to dissolve the carbon deposits, but no more than a quick shot of spray lube after cleaned just to protect it a bit. If you soaked it down heavily with penetrating lube it may have seeped into the motor causing some faults... Just a thought.

No i didn't lubricate it. I just soaked it in carb and choke cleaner. The little spinny thing was stuck solid, after soaking it clinked back and forth nicely.
Maybe I will replace the cps then clear the codes and see if it comes back.

Sounds like a good plan of action to me.

OK, I replaced both exhaust and intake camshaft position sensors and while at it replaced my PS reservoir and hose to the pump. Started the car up and drove to AZ (car ran sluggish) and had the codes cleared. It drove amazing! So snappy and fresh. I was happy... until the next day I started it from cold, and SES popped on and it was sluggish again! I can stop it, restart, and it's much better, but not to where it should be.
Im going to have the codes run again today and see what they say. Any ideas?

It could be fuel starvation as well, you might want to change your fuel filter which is cheaper than the sensors. Stalling and having trouble accelerating will definitively happen with a dirty fuel filter.

Have about 40 miles on a new one already.

This is definitely sensor related. I turn the car off and back on and the problem is gone, and it is completely sporadic.

Paging Weasel!

I was waiting to see what codes popped up... Maybe double check that the vanos solenoid is plugged in really good since it seems to be doing something slightly different now. If it has a flaky connection in that plug it might not activate properly and put vanos in default.

Im on a work trip now but will check first thing, and have codes run and report back asap.

OK Weasel, I ran the codes, and bingo its P0344 cam position sensor again. I've replace both of them! WTF.

Weasel 08-06-2010 07:09 PM

Now that is odd..... I've never seen that code come back after replacing the faulty cam sensors with OEM units. Hopefully it is something simple, I'd double check that the sensor is sitting fully flush, maybe pull in out again just to peek in the hole with a mirror to make sure there isn't any gunk in there. If it wasn't under the intake I'd say check for proper 5v supply and ground at the plug, but it gets power straight from the DME so odds are it isn't the problem unless wires got damaged somewhere, but not likely.
