Ok guys I am back. We got the sportage running but now have a different issue. it run very badly, part of it is bad gas, it was parked for almost 2 year but something else is going on. it acts like it will not change gears. i noticed that a light flashing saying hold comes one. anyone know any thing about this? Is this a emc thing a transmission thing or none of the above. thanks guys you help is greatly appreciated.
If it is the -engine- light that is flashing,
A 'flashing hold light' is telling you the engine is misfiring.
When the ECM detects a misfire condition, the engine has to be running very poorly at that point, the ECM alerts the driver by flashing the engine lamp..
The misfire can be caused by poor quality fuel, a restricted fuel system / clogged fuel filter, an ignition system / spark plug firing issue, or exhaust system restriction / degraded catalytic converter restricting exhaust flow,
or it may be a mechanical issue, involving the valve-train or physical (static) timing of the motor,
Without knowing what tune-up maintenance items have been performed, or (what) parts were replaced by the mechanic(s) that did the original repair on the (??) wiring harness, I cannot be more specific:
(if it was me) I would be contacting the mechanic and discussing the current running state of the vehicle / what options are available to you for further diagnosis and repair.
--
To start, I would be (draining) out the poor quality fuel from the gas tank, and filling with fresh fuel + (adding) high quality fuel cleaning product, like Chevron Techron, or SeaFoam fuel system cleaner.. And would be (replacing) the fuel filter at the same time, to eliminate fuel blockage /restriction at the fuel filter was contributing or causing the issue..
And would recommend performing a full general tune-up: Air filter, Spark plugs, full Oil and Filter change, Coolant inspection and flush/fill if coolant is dull or discolored..
*If the check engine light is on, have the DTC codes stored in the ECM read, if "misfire" codes are present, the above applies..
