I've managed to rack up 100k in two years on my '03 (don't ask). I'm starting to lose pwr across the board now and last night I noticed that it seems that my engine may be starting to miss at idle. No SES light yet, though. On hindsight, the engine has been missing for about 15k miles now while sitting at a light in drive (a/t). Any thoughts here? Coils or MAF?

 

All I know is I have a 2000 and I have the same problem all of a sudden, so hopefully there will be a re-call on those freakin coils. My girlfriend says my car feels like it is going to blow up.. haha

 

Dyno it. . .

 

I dont think the 03 max had any coil problems, might be your maf.
