Re: timing problem on 1990 F150 inline 6
Well for what it's worth.............I had a 91 lincoln town car years ago that was running poorly and I took it to the dealership and they told me that if you removed the piece in the end of that connector it retarted the timing 4 deg. ????? they spent hours test driving etc. and never fixed it. Turned out that the fuel filter was my problem, no thanks to them.....Should be easy to see with a timing light!!!..........Hope that helps.
