'86 BII 5sp
Having an annoying issue with my BII. When you go and start it cold, it will start and idle fine. High idle is OK, normal idle is fine too. However if you try to drive the truck anywhere, it just won't. It will gag and sputter and misfire, and backfire too under a load. Clutch in / no load and it idles and revs fine. Only when it's got a load on it.
However, this is only for the first 5 minutes or so. Once you manage to stumble a quarter mile or so, it'll be A-OK and run fine all day long, around town and highway driving.
So far, I've replaced the IAC and the coolant temp sensor (for the ECU). When I first got the truck two years ago, I also gave it a full tuneup and replaced the distributor with a reman unit, keeping the original Ford module because the generic module that came with the reman dizzy was bad.
I will also note, sometimes I get some gray/black smoke from the exhaust. Like, at first start, and when it's sitting idling for a long time - for instance, when I was charging up the A/C and it basically sat in my driveway idling for about two hours.
Any thoughts?
Thanks,
