...it doesn't run right. It idles. But when I rev it, the motor sounds like it's sputtering at low RPM, but will make it to high RPMs no problem. When driving, it sputters and bucks with load (acceleration or up a hill) - like it's missing. I have a feeling it had something to do with the engine wash. I was leary about getting that part done but these were "professionals" so I thought they knew what they were doing. Any possible valves or hoses got clogged? Where should I check? Any general ideas or comments? Any appreciated...
