I'm starting to think it may be the spark plugs for my problem. I bought some NGK iridiums on ebay and had the mechanic put them in when he did the water pump and timing belt. Maybe one is mis-gapped or something.

For the MAF, I would check your code that the computer puts out. I have a K&N cone type filter and my air flow meter has been fine.

After replacing of timing belt and water pump I've got the same problem. (How) do you solved that problem??

has anyone had this problem before? it fires up fine and the when i drive off it starts to sputter i resete the codes and as soon as i turn on the car it turns on the check light

13 - RPM signal no. 2 This is the one that gives me the miss fire!

27 - Sub-oxygen sensor signal (on left bank)

29 - Sub-oxygen sensor signal (on right bank)

The 27 and 29 are beacuse i have bad o2's and the car has an Exhaust leak by the o2's

can anyone give me any ideas on what to look for???

Hello,

I have a similar problem as you have had (=code 13). Could you please tell me what exactly is meant by: "distributor wires"? Which distributor is meant here?

Thanks and best regards,
