01 sl check engine light

I have an 01 Sl. It's throwing a tune up code. I just had the spark plugs replaced but apparently the "mechanic" my x had fix it put in 2 different sets of spark plugs. Could this be part of the reason the check engine light is on?

    The light is blinking I have checked all fluids, had the oil changed, once in a while another light on the dash comes on that I do not know what it is. I do not have a book to tell me what it is.

    A flashing check engine light is usually caused by a bad missfire what codes do you have?Also have you checked your plugs and wires?

    If it's what I think it is, it's probably the intake gasket is leaking air and that's causing your engine to constantly idle higher than usually at idle and your gas mileage is probably half of what you're used to seeing.

    I got the same code problem a few years ago and some posts on this forum pointed it out to me and I replaced the intake gasket myself back in 2008.
