Started my 1987 4.2L today and it's not running well. It's idling around 1000 rpm, it won't shut off without severely running on, and it bogs when revved in neutral. I set the timing as per the sticker, "9 degrees BTDC @ 1625 rpm. I'm assuming this is with the vaccuum line attached?
I'm guessing the issues are with the vaccuum lines that I have been trying to straighten out. I have an intact diagram on the hood and in the manual, as well as access to another 1987 YJ which the owner claims to be unmolested, engine-wise.
Heck, if anything, it ran better when it was warming up.
Any ideas what I'm missing?
