I’ve been getting CEL P2178 and P2188. Essentially, I’m running rich on and off idle.
So far, I’ve cleaned the throttle body, and MAF sensor.
Replaced spark plugs, purge valve, and air filter.
I’ve checked for degradation of MAF and front O2 sensor wires but found nothing.
I’ve also recently checked for vacuum leaks but didn’t find any.

Aside from the running rich codes, I got P2196 (I think) it was the the O2 sensor was stuck open, this was right after I replaced the purge though then cleared itself and hasn’t returned.

The only other symptoms I’ve had are at idle some sputtering and changes in RPM, this only happens when in drive though. If I shift to neutral it immediately stops. It also only occurs when the engine is warm and has been put under a bit of stress.

If you have any suggestions as to what to do next that’d be great.

Thanks!

Why Does My Vehicle Over Heat When I Get Up To 70 ? As Long As I Drive 55-60 It Is Fine. What Makes It Over Heat On When I Reach 70 Or More ? I Don’t Have Any Antifreeze In It, Would This Be The Reason It Over Heats ? If This Is Not The Cause Please Let Me Know What The Cause Could Be. “O” I Have Changed The Thermostat Twice And This Did Not Help. What Do You Think Is Causing This ? I Will Be More Than Grateful For Any Ideas Or Help. Thanks .

We bought 08 Mazda5 in May 08, and it has 20,300 on the odometer.  Last week, the clutch failed in the middle of the highway.  I started to notice that the clutch was slipping about a week prior to the incident.  The dealer told us that we needed to replace a clutch.  We agreed to replace a clutch, brake pads, air filters, drive belt, and cabin air filter.  They also performed wynn’s fuel/emmision system flush service.   When I picked up my car today, I immediately noticed the awkward sound every time I changed the gear.  Suddenly, the gear got stuck as I was driving  home from the dealer.  When I stopped the car, I saw all the warning lights were off including, engine, battery, engine oil, ABS, power steeling, and air bags.  Moreover, all the electronic gradually died when I was waiting to get the car towed, and I could not start the car.  I didn’t have any problem before I took it for a repair.  What is happening to my car?
