Thread: Two Questions..

I was thinking last night that a couple of years ago I put on a trailer hitch. I used a u-haul harness on it. I followed the instructions, but I better double check those connections first.

As far as the tacoma goes.. would a octaine booster help??

If you did the wiring harness two years ago I doubt it's the source of a new problem, but then again you cannot rule it out. Like Glenn says, use a meter to really hone in on current draw. Most of the newer fuses have two tiny holes on top testpoints.jpg to check them in place. For your problem you can check the amps across the fuse, looking for one that kicks up the reading above a few milliamps. You can also check for blown fuses, positive on each point in turn, negative on a good ground - when you lose 12V on one side you've found the open fuse.

On the tacoma, don't waste money on octane booster. Higher octane slows the burn across the cylinder to prevent "ping" and detonation and will actually hurt mileage on a vehicle that doesn't need the slower burn. The fuel injector cleaning that the dealer is talking about is pulling the injectors and cleaning them out with a precision probe, sized for the injector bore. The liquid cleaners are going to take more time to show improvement, if any. I'd tell her to add injector cleaner to every tank of gas for a couple of months and see if it helps. If not, the injectors could indeed need mechanical cleaning.
