Re: engine revs then bogs when driving
So with the "check engine" light on, there will be a fault code set in the PCM (powertrain control unit). You could try the keydance to retrieve the code(s), or will need to have it scanned. Keydance: ignition switch off/run three times and leave in run at the third time. odometer will show DONE when all ok, or a fault code(s).
