I have a 97 Grand Prix GT and I have a problem whenever i am on the highway going up a large hill and have my cruise control on my car will start to have a slight shake or shudder like the engine is trying to gain RPM to get up the hill but its having trouble. This happens whenever i am going over 40 mph and i push down slightly on the gas to try to gain a little speed. I know its not my OD because it happens when i am not in OD. It also seems like the car isn’t as responsive as it used to be like its a little sluggish. Im thinking it might be a bad cat but i don’t smell anything like rotten eggs and no warning lights or sensors have been triggered. Please help!

An embarrassing problem I know! I think I have hemorrhoids because my rectum is slightly blocked and I’m getting no pleasure from my prostate (I used to).
I’m 18 so I’m not in the prostate problem age bracket but
I’m not experiencing pain with them so they must not be all that serious.
What can I do to get rid of them?

Disclaimer: I’m not a cheater or lazy. There’s a packet due tomorrow and this one page covers material she never taught us. I just need a boost. I figured out most of the page but needed a little assistance on a couple because I couldn’t find the information needed to answer them. Thanks again
