I have a 1993 chevy s10 blazer, 4.3 liter v6. And it will not idle in gear. The idle surges low then back up again.I work at an automotive repair shop and this one has us baffled.I have tried all of the sensors; iac, tps oxy, temp, and every other one. Thought maybe the pick up coil in the distributor. Replaced the control module and tried a new ecm. Any thoughts would be helpful. Thanks.
have the same problem?
