I have a 93 Sundance(4cyl,manual). It has been stuttering lately when I give it between 25%-50% throttle. It seems to stutter worse when it is rainy or humid out. If I give full throttle it accelerates normal. But if I give it anywhere between that 25%-50% range it stutters bad, where the hole car jerks violently at slow speeds and noticably at higher speeds. It seems to do it at a certain RPM range also. I don't have a tach but I would guess it is between the 1500-3000rpm. If I keep the RPM's really low or high(just like throttle under 25% or over 50%) it doesnt seem to do it. I have a check engine light coming on also which I am going to have checked by a friend. I wanted to see what you had to say about it also. Thanks for you time. Will

Hi:
If you scan the computer, chances are it will say random misfire. Has the car been tuned up lately? If it is worse when it is damp out, usually that indicated bad plug wires.

Let me know what you find.
