SOURCE: 1990 454 mercruiser misfire under load when warmed up

Running on a stand is not the same as running under power...In the water, you are essentially running on a dynomometer (dyno is a big water brake) If you can prove that the module isn't putting in enough advance, it would be doing the same thing that I mentioned with the damper, only for a different reason.'re likely on the right track. (rather have a points setup out on the water...anything goes wrong, you fix it without a tow!!!!)
Good luck

What to change in a tune up for a 1990 toyota 4runner

The 1990 had points still or did it have the electronic ignition? There are only a few things to change on the electronic ignition. First the plugs have to go, get some Titanium tips in there, good for 100,000 miles, then some plug wires if you think it needs them, air filter, check all the fluids, coolant, brakes, power steering, battery water, tranny, if it has a dist with points, get a new cap and rotor and a set of points, gap them exactly to spec, or it won't run. run a can of stp through the fuel tank and clean out the injectors, or carb, the oil change doesn't come with a tune up, it comes automatically with the 3 to 5 thousand mile interval.

Were is the fule filtter on 1995 toyota 4runner

Fuel filters for 1995 Toyota 4Runner would be under the vehicle driver's side halfway between front and rear. It is an inline design and would look like the image below. The two (2) ends have threaded openings that connect to the fuel line from the tank and the other going towards the engine.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Take care

Location of fuel filter on a 2003 toyota 4runner

Well the fuel filter is internal meaning its inside your tank and does not need to be changed under regular maintenance you would have to pull out your gas tank to acces I work at a toyota dealership and have never seen one that has needed to be changed due to a drivability issue either hope this helps
