When I begin to push on the throttle peddal it feels stuck then gives way. I hate this. When the 1.7 was in it didn't do this. Just since I put in the 2.0. The butterfly was frozen to the sides of the body when I got the engine & it took a lot of spraying & scraping to free it. I thought I'd sanded & steel wooled it enough. I also thought it might be the way I ahve the linkage connected. Here's a few pics. Can anyone see anything that might cause the stickiness?

Hey Bruce,
I had the same problem. I found that i needed another spring attached to the part that the throttle cable is attached to.
HTH

If the throttle body is worn it will stick closed. Mine used to do this until I swapped TBs. It was the worst when the car was cold in the morning.
