1999 Jaguar XJ8 V8 81000 miles
Have a 1999 Jaguar XJ8, 81k miles.
Purchased it a few months ago and have it checked out at a jaguar dealer, who said everything was fine.
Car has been sitting out, driven about once every 2 weeks. Drove it for about 15-20 miles today before it started idling very roughly. Things were going fine until we stopped somewhere for about a minute, and after I started the car up again the shaking occurred along with a " restricted performance" alert. This has never happened before, and the car has been driven for much more than 15 miles after I purchased it (~100 mi).
So, engine is rough when idling (shaking is gone or covered up when driving) and a " restricted performance" label appears. Also, I haven't tested this extensively yet, but the AC seems to blow hot air after the car started shaking.
I'm a complete novice at cars, but I once had a car that had a coolant leak into one of the engine cylinders causing it to misfire and thus shake, though the shaking was covered up when the car was actually driving.
How likely is this the case? The car has been sitting around in ~95 degree temperatures for a couple days, and it was driven earlier about 7 miles without problems. I know that it costs a couple thousand to have it repaired and if this was the case.=(.
I also noticed something about checking the EGR valve. Is this something that I can do myself, or do I have to go have someone check it out?
What do you guys recommend that I do?
