Hello all,
Have not been on in a while with all the traveling for work. In addition, it has been a XC repair/replace kind of summer. Driver side axle, DS bearing, ball joints, brakes, battery, and on and on.
Problem:
I am having slightly rough idle and poor shifting when the A/C is engaged. It is very obvious that the A/C or the clutch assembly is going bad because when the A/C clicks on, there is a grinding sound just before and just after engagement. During operation it is at acceptable noise levels for a 14-year-old system. The A/C is cold and all controls work properly. It happens on hot days, warm days, and even cool days.
Within minutes of turning on the A/C the engine loses noticeable power (more than normal with A/C on) and it begins to shift like crap. The shifts are sloppy, engage softly, and sometimes there is a slip between second and third gears (Gibbons flush completed 6K ago and B4 done). Once I shut the A/C off a few minutes will go by and presto, running great again.
I replaced spark plugs, replaced air filter, checked all ignition connections, and cleaned the MAF. The engine ran better (without A/C on) once these items were replaced/cleaned/checked. However, with the A/C engaged I go back to the same symptoms.
My guess is the A/C clutch is going bad but that is only a guess.
Any ideas?
Thanks,
Cameron
