Background: I've got 2.5 years and 4k miles on a complete engine rebuild that was done in preparation for the turbo kit. After the job was completed, I was not happy with the work due to the little details the shop missed. I took it back to them, it sat in their lot for a month, and eventually I said **** it and picked it up. It left me wondering how the internals would hold up...
Three weeks ago I started getting a CEL for a #5 cylinder misfire (P0305) along with a pending random misfire P0300. Put in a new spark plug and new Toyota spark plug wires and nothing changed. The main symptom is a very rouge idle, I don't notice anything at driving speeds.
Since nearly everything on this rig is new, including the engine wiring harness, I decided to get a compression test kit from HF. From listening the to fuel injectors with a stethoscope, they sounded fine.
Compression Test:
#1 cylinder = 190
#2 cylinder = 185
#5 cylinder = 90 (tested 3x, including once with a teaspoon of oil and it read the same). I stopped testing compression here.
Next Steps:
The 80 is my DD. Will I make anything worse by continuing to drive as is? Should I disconnect the plug cable from the distributor cap?
I know the only correct answer is to start tearing it down, but I've got to find another drivable vehicle first. My Delta rear bumper was also delivered today lol
