Time to set the timing properly.

Remember to disconnect the timing wire comign from the ECM under the carpet below the glove box. It should be brown and beige colored.

Disconnect the wire, time the vehicle to O TDC, reconnect the wire, remove the negative battery cable from the battery for 5 minutes to reset the computer and you should be good to go.

BlazerLT why the timing?

[BlazerLT]

Because, timing is crucial for your vehicle.

Over time is goes out of adjustment.

having the same problem adjusted the timing runs different but not to performance. how did you find out about the fuel regulator and test it.

Did you remove the timing wire when you were setting the timing with a timing gun?

Were you actually using a timing gun?
