Timing issue, valve adj issue?? Larry @ SP??

My car has been acting really wierd ever since i had the head removed and the valve stem seals replaced. It ran fine before i had this work done. After the car was back together, i tried to run it, and it had a horrible hesitation when i stepped on the gas. I had to double pump the gas pedal to get the rpms to rise. If i just stepped on the gas, it would rev a little, and then die. BTW, i had VPC/AFC in the car at this point. SO i removed the VPC and wired in the AFC only, and reinstalled the stock MAF. THe car runs much better now, but something still isnt right. If i am crusing along on the highway, and i wanna accelerate slightly, or i have to climb a hill, the car will hesitate, and feel like its missing. This usually happens out of boost, and if i put the gas down farther, i will feel smoother acceleration.

So does anyone have any idea if this might be timing related, valve adjustment related, or something else???

Please help!!

sounds like your timing belt may be off a tooth

Does it seem to be in the 2 to 3000 rpm range mostly? If so, I'm having the same problem. I changed the plugs and checked the gap. I'll check the timing belt next.

Yup! I notice it mostly around 2000 to 3000 rpms. How can you tell if the timing belt is off by a tooth??
