1992 S10 Blazer 4x4 4.3 liter just over 160,000 miles.
The service engine light comes on just after start up and remains lit
until the engine warms up, the colder it is outside the longer it
I had it checked and the only code was a 43 (knock sensor?) The voltage
at the sensor was 3.9 vdc which the mechanic said was a little low but
that it should be alright. I also replaced the knock sensor just to be
on the safe side.
No one seems to know why the problem seems to be temperature sensitive,
or what to do about it.
Any comments, hints or suggestions would be a big help.
Thanks folks, Hope you all had a great Thanksgiving. Where
