Sorry to resurrect an ancient thread, but I had exactly the same happen to me. Driving at a steady speed on the motorway, and felt like my foot had gently touched brake pedal - needed a bit more throttle to compensate. Noticed injector light on. After I exited motorway, all the described symptoms as OP and others. Problem is, next day it was back to normal. Injector light no longer lit (does that mean the codes are no longer stored?)
This morning, on way to work, same problem. Not had a chance to read the codes yet. My question is - - where is this wire that is mentioned as the probable culprit? Are we talking in the footwell, by the pedals, or at the fuse block, or in the engine compartment? What colour wire am I looking for? Any help would be appreciated...
Drove it just now -- throttle response normal. After 30 seconds or so, light went out ... so do the codes stay stored, even after light goes out?
If you can play a guitar and harmonica at the same time, like Bob Dylan or Neil Young, you're a genius. But make that extra bit of effort and strap some cymbals to your knees, suddenly people want to get the hell away from you.
