I have an 02 chevy blazer 2wd, v6. Recently when hitting high speeds (50-60) mostly going uphill. It feels like it's not shifting or something. I for some reason have trouble getting past 50-55mph and kind of a pinging or rattling sound is coming from under the hood. I just can't get it to get over 55 uphill at all. The RPM's are reving when I press down the gas, but I'm not getting anymore speed and the temp will move up slightly in doing this. Is this a tansmission issue and if so, what can be done? Car has always run great, but then this. I know it's not a fuel pump as I just got a new one at about 60,000 miles. Can you think of anything?
thanks

Stop at your local exhaust shop and see if the cat converter is plugged. That could also cause your concern. Let me know what you find out

FYI. I needed a new Catalytic Converter and a Mass air flow sensor. Running like a champ now!

THanks allot!
