I recently bought an '87 van with a 302 with EFI. I get some slight
pinging when I accelerate hard or when I come to an upgrade at highway
speed. Seems to run fine otherwise (except occasional erratic shifts
feom the AOD tranny). Our other 2 cars use gas from the same station, a
name brand, so I don't think that's the problem. Does the 87 have a
SPOUT connector with a timing jumper? I can't seem to locate it. Is
there some other procedure on 87's to check the timing?
Any ideas what could be causing this would be appreciated.
Other than the occasional erratic shifting mentioned already, it starts
from cold at a somewhat high rpm, and at high road speed in AOD, the
engine seems to not be able to get to higher rpms. It does not have an
MAF sensor, and has 8 separate injectors.
