I had seen posts about the issue with the length of pipe prior to the MAF and normally have the filter set as far away as it can go and still seal. For testing I ran it even farther as seen below.
I did notice last night that when is started running rough, the boost gauge went from -20 psi to 0 while it was sputtering. As soon as it ran smooth the pressure dropped back to -20. I replaced the vacuum lines before putting the engine in but double checked them all to make sure there was nothing loose. I checked the actuator and it wasn't moving. I pulled the hoses and checked that both sides held vacuum, which they did. So I picked up a new solenoid. It runs way better now, but not great. There is still some surging at idle but I'll wait till it's cooler to see how it drives at speed.
I did pull the fuel line up at the rail last night and it looked like plenty of volume but I haven't checked pressure yet. Once it cools down my test drive might be by Harbor Freight for a pressure gauge.
Although I checked for loose hoses I'm not 100% sure there's no vacuum leak so I'll cap the brake booster line and blow propane to check everything else.
So far: New O2 sensor but it likely needed one. New plugs but they were badly needed. New boost solenoid but it was completely busted.
