Sad day for me /:
today I went and looked at a 90’ b2600i. 256k miles. Which kinda scared me buht after test driving it and looking at the truck it seemed like a solid deal for $1,300. Looked as if if just needed some love.
On my way home the truck stalled. Before stalling it had a rough idle & then as soon as I gave it gas it died. Tried to restart the truck buht it would start. It cranked buht didn’t wanna turn all the way over. After a few times the battery died and I needed a jump.
I got the truck towed back home where I began to inspect the problem. The guy mentioned the the gas cap was incorrect so I went and bought a new one that fit the truck. The battery was also bought 6 years ago so I bought a new one. In the past with my Miata I had a clog Cat and it had a similar problem. So I started with that. I detached the cat gave the guy a try and it fired right up. I was stoked ! I went and did the oil change and all.
I started to flush the radiator, I was letting the truck warm up and I was doing the flush. I say it was in about 15/20 min. Before the trucks idle got very rough and stalled out. I went from stoked to bummed real quick.
Has anyone ran into any similar problems? Or anyone know where I can start? I’m looking into the coolant temp sender now.

 

It's been a few days since your last post, but if you haven't already, check for vacuum leaks, check the spark plugs (might as well replace while out), spark plug wires, coil, distro-cap, make sure to bleed the cooling system, and if all else fails, look into the ECU. This gen of B series are known for issues with the ECU. There is a capacitor inside that is part of the fuel injection circuit. It WILL slowly leak overtime and damages certain sections of the PCB.

Hope this helps, god bless!

 

So I went ahead and checked for vacuum leaks. Found none. I moved onto the spark plugs. I’m noticing them damped in fuel it smells like. What would cause this ? & would this be the issue I ran into ?

 

Its either lost spark, or not enough spark.

 

I went and changed out cap and rotor today as well with plugs and wires. I’m leaning towards the distributor ? Since the issues start once the car is warmed up.
After changing the way plugs wires cap & rotor. I’m still having the same issue. Car was on for about 7 min max before it started to act up again. Once I press throttle it loses power and idle drops. I pulled out my spark plugs. And #4 is totally burnt. Only being ran for 7 min about. #3 not so bad. #2 looks like 4. & #1 is looking good. Also I’m smelling lots of fumes while car is idling.
Could this be head gasket ?

 

You need to actually test the spark coming out of each spark plug wire when cranking.
