knock sensor bad?!?
OK, remember about a month ago (or more) when I was telling you that my
86 5KCST wasn't developing "enough" power? (or at least, it seemed that
way.) I noticed that at highish speeds, I couldn't get the RPMs over
3000 without the check engine light coming on (fault lite). I know that
while driving this lite comes on when there is too much knock and timing
is being retarded the maximum amount, but I didn't think that it should
be coming on at 70 mph w/91 gas...correct?
OK well no matter HOW we feel about that stuff, I finally ran the codes
on the engine (two times w/two drives to verify) and I get engine code
2142. According to the bentley, this is "knock sensor wiring or knock
sensor defective". That's about ALL that they tell me. Period. All the
other sensors/wiring thingies have much more troubleshooting info. This
one they seem to have dropped in my lap.
OK! I say. The computer concurs that there is something wrong with the
knock protection. But where do I go from here?
BTW -- as an aside, a little question in relation to my motorized antenna
saga: why does that clear vacuum hose attach to the bottom of the
factory motorized antenna?
