Build high compression ls/vtec. First thing I have trouble.

1. When I start the car, it starts, than dies. When I hold on the gas pedal until it's warm enough the car's idle fines. Loose vacuum? Check all the vacuum and everything seems fine. Any suggestion?

2. After checking my spark plug, it was dark. carbon build up I'm guessing. timing?

3. The rpm flutters when I drive past 2.5k-3k rpm.

4. When trying to speed up and stepping down on the gas pedal the car studder and feels like it has no power than drives fine after a certain point.

Any help will be great.

The ecu is chip with a ls/vtec high compression. Still need to be tune.

 

check the timing possibly, and cels?

 

bump, Thats my suggestion too, dont have time to do timing but the timing belt is getting rub on by something cause the side is peeling off.

 

i wuld do a compression check to make sure your timing is right and everything is mechanically sound. check ignition timing and if it still acts up get it tuned. your chip isnt tuned to your car specific. Or try another ecu with the chip or another high compression chip.

 

did compression test. Came up 215/215/200/200. No CEL. maybe I'll just go get it tune and check out at kings.
