GMC Repair: Throttle position sensor, fuel line filter, throttle position sensor

Question
Thanks you for your time.  My question is about the TPS on a 92 GMC Safari van, I recently replaced the Oxgen sensor on the Exaust pipe and then had a fuel line filter replaced and a new fuel pump. It was after all this was done the Van started useing alot of fuel I rechecked the error codes and I am recieving a code 22, now as I have replaced the Oxygen sensor, I am lead to belive my next sensor would be the TPS. If I am heading in the right direction any help would be aprieciated.  
Thank you.

Answer
This would be a TPS fault. Some of the TPS's MUST be adjusted and some require NO adjustment. If your TPS has SLOTTED holes where the screws hold it onto the throttle body this would require the TPS to be ADJUSTED. If the holes are perfectly round then NO adjustment is necessary.
