Intermittent Problem
85 A4.
Every once in a while, the car will start, and run like absolute ****. Will idle, but its all over the map. It only does this like 1 in 10 times I start it, and seems to be completely random. It does it when its hot, cold, or anywhere in between.. During this time, its runs VERY rich. It will move, and at about 55 mph, my instant mpg is 10. When its running normal, my 55 mph readout is usually 28-30.
I'm thinking that its an injector thats clogged, so the other injectors on that bank just inject a whole ****load of fuel, to make up for the cylinder thats running lean.
What do you guys think?
