Is there a problem or is it common for my 03 to have a slight miss when my A/C is on?

 

I think my '01 is doing the same thing. Anyone have any opinions about this?

 

try running gas treatment and fill it up with 93 octane the load of the a/c can make them do that if the motor has carbon build up in it

 

I just ran a can of seafoam through mine in the last few months and occasionally run a tank of 93 through. Any other suggestions?

 

the a/c puts quite a noticable load on them when the clutch kicks underdrive pulleys make a big difference on that part but weak fuel pump or ignition also i would need to know more about the problem description and what all has been tryed ect to get more precise could be vacuum leek in HVAC system also

 

I posted a thread on this same problem a few weeks ago with no response..lol my 95 just started doing this too, engine has little over 3000 miles on it and everything is new all new vac hoses rad,water pump, spider,fuel pump, fuel filter..etc i cant feel the mis but it sets off the ses light with a #1 cyl misfire..ign system is new also and double checked..

 

You got a lot of responses in the original thread you created. The latest one was just a double post...
