When was the last tune up? Also, cleaning the throttle body would be a good idea.

Thanks Mike i did all of that but I wouldn't believe it in a million years come to find out it was the up stream oxygen sensor it was reading 1.012 on my machine instead of the rang 0.900 to 0.100

Wow, good job figuring that out! That's weird, a bad o2 should have thrown a code. Thanks for posting your fix it could help someone else. 1
