1992 Chevy Blazer 6 cyl Four Wheel Drive Automatic
92 Blazer 4.3 CPI.
Replaced eng. After timing adjustment engine ran fine. On the second test run the engine died just as I was turning into my drive way. Now when I start the engine sound like it has a big cam in it as it lopes.
I have checked for vacuum leaks by spraying carb. Cleaner around the intake--no change. I pulled and cleaned the IAC. I have not done the ohms check of the IAC--will do today.
One thing I did notice is if you remove the hose from the brake booster the loping stops but the Fidel is some what high.
What type vacuum reading should I have from the intake port on the rear of intake?
thanks for any help.
have the same problem?
