I put in new injectors (a month ago) then saved up and got a rebuilt pump. Both from a recommended rebuilder.
She starts instantly and idles great. The high idle solenoid seems to be working and the idle drops after a couple minutes.
There's a quick puff of black smoke at startup and then some almost invisible smoke from then on that doesn't go away even when up to full temp.
That same slight smoke is still there while cruising and normal acceleration. And she goes like hell now! (compared to before).
If I get on the throttle a bit more it rolls coal very easily. Seems like too easily.
And one other thing, that may not be relevant, I've had it stall when coming to a stop unless I come in easy and keep a bit of pedal on to let her wind down gradually. Then it sits at idle nicely. At idle, in park, if I do a quick stab at the throttle it will quit almost instantly after I let off.
My pump mark is turned about an 1/8" toward the passenger fender. I read here somewhere that if it rolls coal easily then the pump is turned too far in that direction. But 1/8" doesn't sound like very much compared to what I've read here?
I turned up the idle adjustment but that just made it rev higher and I still got the letoff stall so I turned it back down.
That's all I've done.
Then I drove it today and the stall at letoff is gone. It returns to idle nicely with no stall. Even if I do a quick stab while sitting in park.
But today the engine sounds "clacky". Where did that come from?
What the heck is going on?
I was going to take it to camp tomorrow which would put me on the freeway for the 1st time since I got this truck.
Now I'm afraid I'm gonna cook it if I go 65mph for 1/2 an hour. :-(
