engine light

Does your VX make a farty kind of sound during acceleration? I would check the mounting of the EGR valve and the attachment of the tube coming off the passenger side exhaust manifold that feeds the EGR valve. Letting air into the exhaust stream can fool the O2 sensor into thinking the bank is running too lean and then the computer tries to richen up the lean cylinders. This causes the idle to vary and then the computer tries to compensate with the IAC.

No farty sound. When driving all is fine, maybe a little miss when idling at stop.
Main thing is the revs going up and down on start up and solid engine light on.
should be changing some parts next week will update.
