FotiosF90M5 · 08-09-2009, 06:56 PM

Does anyone know what this code means? 10703 on procede and it showed up as a ses light. Its not in the code chart. Any help would be appreciated...thanks

10703 converted to hex is 29CF. And 29CF is the hex code or Misfire Cylinder 3.

Why not just change the plugs?

think that would take care of it? last time they replaced a coil and injector. Id rather just swap the plugs myself.

Yes, that is far more likely to fix it. Especially if your plugs are oldish (10k+ miles). Spark plug replacements should be done, IMHO, every 10-15k miles in cars running a >14psi tune.

problem went away for a while and has now come back. Time to get the tool and get this done...anyone else throw this code and changed plugs? If so did it completely take care of the issue?

I changed my plugs at just under 10k

Car would misfire in 6 and would idle harshly. Changed the plugs and no longer have any problems.

are you guys mostly just using the stock plugs? I never really found for sure if improved (like NGK?) came out...
