2004 1.4, 16v, EPC Fault Light problem - wrangler_rover
My wife drove the car this morning, after a mile, the EPC light came on, the steering felt light and the car felt sluggish. After parking up for a few minutes, the engine was restarted & sounded weak. She took it to a local independant who recommended we take it to the main dealer, en route to the main dealer the light went out & the car felt normal.
The handbook says "EPC or exhaust emission system fault" The fault appears to be intermittent.
Does anybody have any ideas what it could be?

Strictly speaking; the EPC light is specifically for a fault with the "fly-by-wire" electronic throttle controls. In reality; it can come on for all sorts of engine management faults.

The fact that the steering went light would suggest that checking the charge voltage is correct might be a good start. It shouldn't be in excess of 14.2 volts with no load.
