Is there B+ voltage to the injector ? Is the engine computer controlling it ? Suggest you watch youtube videos on injector control . Inside the PCM - engine computer are transistors which control the injector.

If it's anything like my 1994 Vandura, you have a small panel of rocker switchers above the rearview mirror for turning your interior lights and other gadgets(tv, vcr, etc) off and on.

The leftmost switch on mine moves the electric bench seat up and down, *and* forward and back. The trick is that you have to hold it down to make it move.

With mine, even though there are four actions:
- slide seat forward
- slide seat backward
- fold seat down
- fold seat up
there is only one rocker switch.

So what you do is hold "up" on the switch and see what it does. If it slides the seat in either direction, up for your van is for both sliding forward *and* back. To do the opposite direction, just wait a second then press the same button the same way a second time.

If up makes it fold, it's the same principle. Hold the rocker switch depressed in the up position to make it fold up. Wait a moment and repeat to make it go down.

It wasn't intuitive for me either but once you know and play with it a bit it makes sense. Probably better than having four switches up there anyway :)

Good luck!

remove the oil filter and check that there are not 2 rubber gaskets in place (one in the filter and the old one that was stuck to the engine and came out of the old filter.) refit using a smear of grease ?oil on the rubber gasket and do up till it touches then about a 1/4 more turn . Do not over tighten or it will leak

There could be all kinds of reasons your vehicle runs rich. It should be fuel injected not carborated. It could have a bad injector, bad air filter, o2 sensors etc. Have it scaned for the reason.
