Ford Repair Questions? Ask a Mechanic for Answers ASAP
have they cleaned or replaced the mass air flow sensor? Has the iac been changed?
Has the iac been changed?
(iac) idle air control on the throttle body
no codes at all ?
does it run good? is the check engine light on or flashing?
does it shake n shutter ? doess it feel like a loss of fuel ? or a loss of ignition?
its one of 2 things its a bad IAC or a bad ac compressor
no it would not...the ac system is not connected to any warning lights...
Your description tells me there is a excessive load when the compressor kicks on. This means its ruled down to a idle air control valve not adjusting correct or a internal air compressor issue
with the ac on or off?
will it stall with the ac off ? if you put a ps strain on the system?
then its the iac...i would replace the IAc with a ford one..and inspect the throttle body closely for damage...a reman throttle bottle may be the best option
