Hi,

I'll letr you know if there is a user manual available

you will probably have a few sensors where the plugs might be different but other than that you should be able to

will work might have a few sensors with different plugs but shouldnt be to bad

Check for a broken hose at the pcv valve and make sure the plug did not get dropped while tring to install also you can swap the plug with another one or with another cylinder and see if the miss follows the plug or stays with #5 if it stays with 5 a compression check and a leak down test will most likely tell if there are any other problems

need a wiring diagram for a 1999 chevy blazer 4.3 4x4... had to replace motor and now the 4x4 wont work... anyone know where u can print off the diagram

If there is no switch present then it is full time 4X4, it does not disengage, good for travel bad for fuel mileage.

The actuator can be tested with hand vacuum tester. I don't believe it will work without the actuator.

this just jumps to the other large post (battery power) on the starter -jeff please rate
