I just had the heads done on my '90 Vanagon, it's back
together, it's not running well and the mechanic is
stumped. It runs when cold, as it warms up it runs
very rough and rich, black exhaust, etc. He has
checked the engine ground, the wiring, changed the o2
sensor, checked air control unit, changed the temp
sensor, even tried a different ECU ...all to no avail.
I've seen this same problem (after valve/head work)
posted on a tech site...but couldn't glean a solution
from the listing. Any suggestions out there?
