Ever have a gremlin you chase for a while to no avail, only to stumble onto something bonehead simple as the culprit? The kinda deal where you hesitate to tell buddies cause you know they'll give you a ration of bs? I had that today.
Installed a trd 2nd gen supercharger a couple days ago. Ran awesome on a quick lap around the block. Came back, and cleaned up the details-nicely routed and loomed all the vacuum lines, bolted the wire looms onto driver side of s/c etc. Since then I've had a violent miss under 1/2 throttle or more above about 3k rpm. Did some searches, ended up:
-changed fuel filter (way overdue-like 250k overdue)
-free FMU mod (fuel regulator connects to boost to up pressure)
-extensively looked for vacuum leaks
-hose clamps on vacuum/boost lines
-changed spark plugs to ik22's and in the process, I see this:
When I bolted that loom up to s/c, I failed to see my plug wire needed to be slide through the loom a bit farther. The plug pulled up and loose. I fixed it, and ran around the block again to see-yup all fixed, hauls butt and no miss or pinging.
Felt stupid and happy at the same time.
