92 SE running on 3 cyl

[BLACK91GT]

Hey there,

Just thought that one of you guys may have an idea of what I should check on my SE.

This one has 380000Km's.

On Sat i was coming from T.O. to Cambridge on the highway, I was cruising at 160km/h for quite some time with no problems, then when i turned off the hwy i noticed that she was running on 3 cyls.
Now when the car idles or at slow speeds it misses, but when i floor it or am on the hwy at 140~ it runs fine.
I am hoping it is just the plugs...

Any one have any idea's of what else to check?

Thanks

i think it would be time for a tune up. plugs, wires, air filter etc...

I know, I know,

Actually I have done proper maintenance to this car,

5K oil and the wires, plugs etc were changed in the spring

I dont want to spend too much on this car at this point with the K's on it, and since i now have my replacement 91 GT...

Nah,

It hasn't rained in my area since before the weekend, before the problem started anyway. I doubt it would be that, but i will keep that in mind for those rainy days....
