Jim,
I read your write up on the palm scanner, is that the scanner you are currently using?

I have not used a scanner before. I have a 97 s420 that has the individual electronic ignition modules on the spark plugs. Will the scanner be able to tell me which one is bad if one should fail?

I'm trying to decide which scanner to buy. I read a thread by Steve about the SnapOn MT2500 scanner. He said that the MT2500 will give you about 75% of the information about a car as compared to some other OBDII scanners that only give you 10%.

Having tested the Palm scanner what are your thoughts?

Thanks,
Tom
