Air intake maf

Wrangler. Cardone says there is not one? why not say why you think its bad, or why you want one,????? a science fair experiment? great question. are you in USA< locations matter , buying parts!!! but you failed to say what engine? 4L or 2.5L (neither have a mAF) the both engines, I have both i 2 cars. use MAP sensors. The speed density system. neither use the Air density system. let me guess, car runs crappy and guy on bar stool said, bad maf. rigth. (just joking, it was a web bunny guy who said it) better is to post the symtoms and ask for wild guessing or ask for the tests, (me) and never pick the most expensive part on top change , guessing. try a tuneup first.

Where are the drain and fill plugs on the manual transmission of my 1990 jeep yj it has a 4.2 -6

There should be a plug on the bottom of the transmission to drain and a plug on the side to fill it. No spark could be a relay or the coil among other things. You may need a shop manual and wiring diagram to troubleshoot the ignition system.
