Thought it was the timing and tried to move the dist. around a bit, but no luck. When the vtec kicks in it starts sputtering almost two wher it sounds like constant backfiring??? It started after I replaced the old dist because of a bad bearing.

 

constant backfiring seems like fuel cut to me? i don't know though mang

 

ok i have the same motor and lets go thru all the steps....to me sounds like timing prob...ok..did the distributor come with car??? if yes or no replalce ignitor and cap and rotor if u havnt already...also make sure u have all connection like vtec and running a vtec ecu...preferably a p28...reaplce all spark plugs....my ignitor and coil inside were toast so replace it all just to be sure its not the distributor...also is it a vtec distributor?

 

The distributor I had before worked fine until the bearing went. Then I replaced the distributor with one from this guy's d16z6 which he claimed has less than 5000 miles on it. The ecu and vtec are fine because they were working perfectly before.

 

In this case what would be the remedy?

 

ok does the engine run fine at idle???...and make sure the timing is set correctly....having it too advanced or too retarded will get u that rev cut sound

 

The motor runs perfectly at idle, but as soon as you rev it around 3800, it starts sputtering.

 

Sounds like the CAS... CRANK ANGLE SENSOR...

ignition problems....id just check your wires and plugs.

sounds like something wrong with the fuel lines

 

What is the crank angle sensor?
It isn't the plugs or wires, I checked.
If it is the fuel lines, where should I begin to check?

 

Crank Angle Sensor is inside the dizzy... are you throwing any codes? I believe it is a code 4

 

no codes, what so ever, but my autometer tach bounces all the way to 10grand as soon as I'm over 4000rpm
