Jim, thanks for the response.

The car has just under 12,000 miles and not driven a lot (1,000/year and stored in winter).

I've been doing some more research since I posted and came across the DMF issue as you suggest. Sounds like the problem to me, although I know I need and to replace the slave and bleed the clutch hydraulic system. From reading some info on the ZFDoc site, the system needs maintenance.

I wouldn't say I have a bad mis or real rough idle but I'm going to listen more closely tonight. As I said, the noise has been getting worse over the last few weeks and definately gets worse after warm up (which correlates to the injectors failing more as they heat up) and I kind of noticed a drop in performance last night. I also know I have a vacuum leak under the plenum so I was going to do a pull as next winter's project but it looks like that may have to be moved up. From what I've read, I'm sure the injectors are, or are going bad.

I mainly wanted to get a direction of where to start.

Again thanks for your suggestions and It's nice to know there is help near by if I need it.
