I've noticed recently that the engine seems to take a bit more effort to start. Previously, a quick turn of the key and she fired right up. Now, I find that I have to crank it for a few seconds before it gets going. Then, it runs just as expected. Has anyone experienced this? I'm thinking it may be clogged injectors or fouled plugs, and I plan to put some SeaFoam in the tank to see if that helps. But, I thought I'd check with you guys to see if I should check anything else.
