Recently when I turn on my heater or a/c my car stumbles really bad. I relocated the HVAC controls to where the cd player should be, and the cd player sits above them. I was wondering if it could be a vaccum leak of some sort?

But wouldnt that cause it to stumble all the time, or just when the controls were on if it was leaking off of one of those vaccum lines that the controls hook to?

dont think it'd be a vacuum leak... thinking more ignition or general electrical problem. When is the last time you checked your plugs, wires, cap and rotor?

Does it do it anytime the heater or A/C is on or just when you first turn them on?

Might also possibly be your battery or alternator.

 

Since you have a MAF car, it's probably unmetered air entering the intake. That would be an alternative expression that means "vacuum leak".

If it's the heater specifically, and even more specifically whenever you turn the temp up off of full cold, then it's the vacuum line that goes to the heater control valve disconnected. Either in the dash or under the hood.

 

I changed all my plugs/wires/ cap and rotor about 2 months ago. It does it only when i first turn the switch to a/c or heat or whatever, but if i go wot while they are turned on it will go wot then cut out then go wot ..........

 

btt Any Ideas? Things I can check? Also when im driving along, sometimes my right blinker will light up and stay on constantly. If im driving with the headlights on and it happens, the right headlight cuts out until the blinker starts to blink, and it always blinks slower than the left, but if you put the emergency flashers on, then its okay. Any ideas?
