When I give it a little fuel, the motor seems to improve. I’d say at around 2000 rpms (guessing, I don’t have a tach), the motor seems a bit smoother and gains more power, and it seems to maintain that as rpms continue to increase. But that idle and up to 2000 is real rough. Very little power to move the truck until the motor has more spin.

I don’t really know what ‘normal’ power feels like in this truck, but I’d suspect that even at higher rpms, I don’t think I’m getting full power, but it does feel improved.

I’ll make a video so you can listen (and see) it with some play on the throttle.

Last night a rabbit-hole of thought led me to consider checking the injectors. What’s the best way to reach the passenger side injectors?

I’m also going to use an old (good) plug on all the wires to make sure each is firing (one-by-one).

Here’s a video of a cold start and some throttle applied: https://www.dropbox.com/s/diln5v5j5a..._6763.MOV?dl=0
