I'm relatively new to the forum but had my 08 TL-S since new with 44000 miles on it. Luckily, I've had no issues at all but recently noticed that when I have the AC on and starting from a full stop, the engine hesitates a bit then catches and goes.

It doesn't happen all the time and just seems to be the AC and not when the heat is on. Any ideas? Thanks for the help.

 

The AC is a huge load (so to speak) on the engine so it's pretty common for it to rob performance while its running.

 

^ thats is correct

 

The added strain definitely makes a difference in how the car reacts...
Lucky for me I drive mostly highway so I do windows open most of the time. A big reason is what you just mentioned, too.

 

I had a 1999 corolla.
to merge on the freeway, i had to shut the A/C down completely!

 

common problems that I face too....

 

my point being, every vehicle will have A/C strain.......


or
you can do what Vill069 did.

 

yep, no AC drag for me! no AC weight neither!

 

 

I had a 93, even worse. I sometimes had to downshift my 3 speed AT to merge
