I've been slowly trying to get my 87 2.9 to run like it should. I did the basics;pulled a plug or two, changed the fuel filter,(cleaned k&n air filter), replaced vacuum lines, battery cables, cleaned all sensor and electrical connectors, pulled the codes and even swapped out the computer and still nothing. I got some more advice here on the 'forums' and replaced the distributor module and fuel regulator and it ran a little better.My 10 year old muffler was ready to rust off so I helped it off with a saw-zall. The cats still need to be checked.With the Ranger still not right, I finally went down each cylinder and replaced the spark plug, checked the plug wires for spark and did a compression check. I found 1 bad wire. The engine runs better than it has in probably a year. The compression was 148 to 150 in all cylinders.It idles with 15# of vacuum. Scrape up some money to get the exhaust done and getter smogged and we'll be ready for the summer.Hope this might help someone else having the same struggles that I went through.........
