Mazda MPV 2004 - Stutters, check engine light came on

Hoping you guy's can narrow this down before I get raped at a dealer service center.

Driving along at hwy speed, the engine for no reason started to stutter.. felt like a miss fire, or even like a transmission gear change..

Engine light came on,.. first flashing,.. then on solid. It made it home, stuttering all the way.. give it gas, and struggles, stutters harder..

In the drive way, in park, Idling, ,. feels like it want s to stall,..revving up to 1000 rpm, then slows,.. up again,..down again,. struggling.

Is this the coils I read about?
PS: 75,000 KM, and other wise is like new. No tow kit.

Chances are fairly good it's the coils - I've posted about this on Edmunds. the OEM design is truely idiotic & has a vent that allows moisture down into the plug well - that shorts the spark & causes misfires. On our 2004 MPV I got away w/cleaning & drying them extremely carefully then sealing the vent w/silicone as a temp measure, then ordered perfect replacement after-market coils off ebay that sealed the wells & stopped the problem -and- were a tiny fraction of the OEM price.  good luck, BK
