Thanks to all the folks who respond to questions from those in need. Just by searching the website I have been able to diagnose and repair my 1994 LX with the 1.9l engine. I had a coolant leak. I could not find the source until searching the archives I learned there is a block plug located behind the flywheel. Using the site again, I learned how to pull the half shafts and tranny to get to the plug. Boy was I glad it actually was the source of the leak. Next issue was a idle and stalling problem. Used FEOA and was thinking IAC valve which I cleaned but no go. As the problem started to go beyond just the idle I figured "not IAC". Hmm, back to the web site. Vacuum leak? Tried PCV and elbow, Nope. Intake manifold gasket? YES Carb cleaner test showed where. Couple hours later back on the road and running great. I also did the heater core with help from the website. I feel like I am getting to know the car pretty well and may be able to help someone who needs it like I have been helped. Thanks again all.
