Hi, I'm having problems with my ka24de. When you first accelerate it has a very rough start, it spits/sputters, then once at a higher speed it runs a bit smoother...any ideas what could be causing this problem ? Already changed spark plug wires..but that's it. Think it could be a fuel problem ? maybe I need a new fuel regulator ? help please thanks

Check your timing.

Have you checked anything out at all?
Injectors, spark plugs, electrical connections, fuses, vacuum lines, etc?
ECU throwing any codes?

do a compression test... it might be bad rings, bad valves, or a headgasket. Did you notice any smoke out the tail pipe. White smoke to be specific?

spark plugs are good, and fixed the vacuum leak. haven't really gotten any further than that. haven't checked the codes yet
