Any one ever had a check engine code saying injector four firing improperly? It only comes on sometimes not all the time. Also ABS and brake light on and the speedometer doesn't always work. Sometimes it works from the start sometimes, sometimes at 25, 35, and sometimes at 40 any ideas?

You mean a misfire on #4? Could be anything from bad wiring to a bad injector. Try some fuel system cleaner, or swapping the injector to a different cylinder to see if the problem follows.

The ABS/Brake light thing is usually the speed sensor in the rear diff.

Do a search on the forums and you'll find a ton of info about that.

Like Jason said, the speed sensor in the rear axle.

Here's a link :D

the code actually comes up as firing improperly not a missfire. I just put some injector cleaner through it right before it threw the code.
