HI all

I bought a 2001 XK8 from a dealer in Vegas. It has 100K miles but is in cherry condition. OMG - amazing. My guy took it to his mechanic who checked it out and thought it was a great deal.

All was well til I started the drive home to SF - when the engine light came on. Misfire on Cylinder 2 and 4. That was 6 weeks ago and we're still trying to figure it out. Here's what we've done:

• replaced ALL sparks and coils
• 100K service (belt, fluids etc)

Im still getting the light. Now we're doing a compression test to see what comes back.

Can you folks share what you'd look for in the compression test and what you'd do next based on the results? Im working with a mechanic who isnt a Jag specialist but is a good strong tech. So with a little help, I'm hoping we can solve this.

What I read as potential problems are:

injectors (blocked or bad)
Seals (but there's no oil in the spark plug channel)

What else???

THX MUCH!!!
