Bad Idle cold too
Last week, after tooling around getting the engine temp up, I stopped at a store (looking for a good single malt scotch, truth be known). When I came out, the car was hard to start, barely held idle and was jittery in that respect the whole ride home.
Well, into the garage it went, until this morning.
Same story.
Cold start barely worked, idle was very rough, smell of gas was evident. Now, on reving the engine, the power was certainly there - but the idle was weak. After getting oil temp over 80, it held idle on it's own - barely.
Where should I start?
Prior to last weeks episode, it ran fine the few times I took it out over the winter.

If you're smelling gas - too much fuel. Either an injector is stuck open or it isn't firing. Maybe easiest to pull the plugs and see if you can identify a cylinder or cylinders. I wouldn't run it again until you know, especially if there's raw fuel coming out of the tailpipe - it could catch on fire, blow a headgasket, bend a rod, etc.
