5.3 power?

I'm going to put some fuel system cleaner in my tank today to make sure my injectors are clean. Any way I can test the MAF sensor?

You have something wrong... you shouldn't tell a difference with or withouy the a/c.

AC makes zero difference in my truck.

Mine either The last time I had A/C make a difference was in my 2.8L powered '93 S-10 back in the day and the power output of that thing was also affected by a bag of groceries in the bed so that ain't saying much

2.8L is golf cart motir

I noticed my lights dimmed when I was driving last night and put the back windows up at the same time. Is it possible that this is related to the electrical system? I hooked up my scanner and there aren't any stored codes. How should I go about diagnosing the problem?

Have you had your alternator and battery checked out?

You guys are funny. I pulled a 3000 lbs tent trailer this weekend and it makes a difference if the AC is on or not. A 20hp reduction in power with the AC on you can feel. I went up some pretty steep inclines and it struggled a bit, I just used the tow/haul button and all was fine. Granted most of the turns and hills (up and down) I would not do the posted 55mph with a trailer so did not really notice a major reduction in speed. 308 ft of elevation to 6000 ft in 60 miles there are a few steep hills.

Well, when my fuel pump died a couple months ago, I killed the battery trying to get her running. Mechanic that replaced the fuel pump said the battery was fine after he charged it up for me. Didn't exactly check the alternator.
I run a 300Watt amp and sub if it makes any difference
