I got a problem with my B18B in an EK. It ran fine for a little over a year, but now it just doesnt run right. When I'm driving I get this resistance/loss of power feeling, so I tried flooring it then it just speeds up right after a certain point. Its weird there isnt a specific time it happens. Also one thing I noticed it idles like it wants to die after its a little warm.

 

check the spark plugs/wires, if not that check the fuel pump.

 

Jumped timing belt?
