In the process of running down one thing after another, took the ‘74 2.0 out for a drive. Had a miss, so pulled the plugs. This car has spent a lot of the last 9 years sitting, so gas tank has been cleaned and fuel lines changed.
#2 showed where a plug wire was barely attached which was quickly fixed, but the #3 plug was white. I mean really white. Like zero fuel lean. After looking at the connection to the injector, I saw the boot was ripped and the connection was pretty dirty, so I took i apart and sprayed electrical cleaner in it Drove it a couple miles, still had a miss, but when I pulled the #3 plug now it was black. Did I wake something up? Pulling the engine soon to fix oil leaks, so is it worth it to pull all the injectors and get them rebuilt? I have no idea what’s going on here. On another note, what’s the best manual for a 914 2.0? TIA Rob |

Get a noid lite tester to check that your getting current to the injector. Less than $10. (IMG:style_emoticons/default/beerchug.gif) |
