Ok thanks. Watched a few. Is it true that it’s ok to move the throttle while cleaning? Was just going to use an old tooth brush.IMO, best to watch at least 3 you tubes for this. Use the cleaner available at the parts store and follow the directions but watching it done would help me and help with memory.
Yup its drive by wire.I recommend cleaning the throttle body off the rig and when remove, if the o-ring seal looks good, it can be reused. Since you are drive by wire, I highly recommend that you do not move the throttle plate during cleaning. That is why you take it off, for access to the rear as well as the front. If you do move the throttle plate, it will likely not idle right and then have to drive for a while to re-calibrate the system, so best not to move that throttle plate. I would just get a new seal, for just in case but if was me, I always replace with new seal if I take the throttle body off for any reason. I use a very thin film of petroleum jelly to help hold the new seal in place during throttle body reinstall. Use a soft bristled tooth brush to help clean. You said 2003, so should be drive by wire but if is a cable design, you can move throttle plate but I still would not do a wide open throttle.
Maybe a new filter will help move more air. A good quality paper filter that gets replaced once in a while can often do more for performance than the wire mesh filters that get scrubbed clean. Depending on how long that mesh filter has been at work, you can scrub 'til the cows come home and still have a lot of the filter pores clogged with dirt.All right so got it off. I appear to have an aftermarket one with a spacer. View attachment 384534Looks good and dirty.
