Kia Sedona just got it two hours ago from mechanic. He determined that one coil was broken and the cam sensor need to be replaced. When I got the vehicle from the shop the engine light was out. But when first starting it idled rough and seemed to skip. Drove a liitle ways and the engine light came on again. Any ideas about what the problem could be?
It is so funny you take a car to a mechanic to fix and fix nothing?do you have a module for coils?
Idling rough and misfiring are indications of a problem injector/s , low fuel pressure as well as electronics
obviously the mechanic did not use a scan tool to determine the problem area and is fixing by replacing
Take it to an accredited service center that works on your make of car, have the codes read first then get a quote for repairs
repairing by replacement is costly for you so find a shop that knows the procedure for trouble shooting
Hello
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully
electronically controlled by a computer called the PCM and TCM (Power
Train Control Module, Transmission Control Module). When a problem
like this or other drive-ability related problems occurs the computer
stores a record of the problem (there are of course some exceptions
to this, like the fuel pump, engine coolant temperature sensor and
MAF sensor for instance) in the form of a fault code in its memory,
to read these fault codes you must have the systems memory scanned
with a special tool. Once the fault code(s) are read you then must
perform the appropriate diagnostic testing to find and resolve the
problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED
TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD
EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always
check fuel pressure for correct spec for your make and engine type.
