Engine problem
2002 Chevy S-10 V6 Four Wheel Drive Automatic 150000 miles
----------------------------------------------------------------
At idle the engine runs fine but when you start to drive it, it starts to hesitate, the rpm's jump up and down and it don't go away, no check engine light is on, its been going on now for a couple months and is getting worse, tried to clean intake witch was dirty and it helped a little for a couple days and now its back again.

Possibly might be the multiport injector assy. There is a TSB on this. You can see the header information out at alldata.com.
