Question about 1994 Jeep Grand Cherokee
I have the problem of the vehicle shutting down as I am driving that is after the car is warmed up. But my concern at this point is that I cannot pass emmisions and need to figure out what is going on in order to get my tag.
Want to "cheat" on the emissions thing? Add about 3oz of acetone to the fuel,,, Generally, this will clean it up temporarily. Check your ignition system and LOOK at the spark plugs for fouling etc. Acetone will also help clean the injectors. Is compression and oil consumption normal? Are filters clean? Is spark "hot" ?
I can't be too specific with this answer simply because there are numerous causes for your problem. Since sensors feed off one another, sometimes one thing looks like something else. Therefore, checking all the basicsis important before getting into the more complex stuff.
