The FC starts up right away no problems
Strong steady Idle

I've been experiencing like boggy acceleration
When I accelerate above 2-3k rpm's, and then shift up it's starts to hesistate

Also when I start her up, the FC gets low oil pressure at about 10-20 oil pressure but then when I start to drive, the oil pressure starts to go above 30

I feel like the engine lacks power, when I shift to 2nd gear and then I start to press on the gas pedal a little bit harder, the FC just starts to bog after that

Has someone ever experienced this before?
Possible symptons?

Could be a gazillion things. Search for "poor acceleration" and such. Also, go to your local book store, grab a haynes manual and look at the trouble shooting guide up front. Lots of good starting points ther. I'd check plugs,and fuel supply at injectors,then comp test and change fuel filter...but that's just me.

I have a Haynes Manual
I'm going to check out the Metering Oil Pump to see if that's the symptom

K I found out the FC is in Limp Mode

I just finished buying a Metering Oil Pump (Electric) for $150, not bad.
On MazdaTrix, they're selling Metering Oil Pump for $1,568

I'll post when I get it installed this Morning and see how it goes.

First thing I would have checked is the cats if you have cats! If they are clogged they will rob your car of power. I am not sure if they woulld affect the oil pressure though! Might be worth looking into.

Check the TPS.

These are possible solutions, not symptoms. The symptom is crappy acceleration.

Ah i could have sold you a eletric omp for much cheaper!!!

I would check the compression first.

Sounds similar to what my car was doing - power loss. I do not notice an oil pressure loss in mine, but I did not look for it. Mine did seems to take longer to get the oil pressure to normal. My car also was running close to midpoint on the temp scale. Before, it only went to 1/4 on scale.

Found out I have no compression on the rear rotor.

I was replacing parts that could be a problem, like you, and none helped.

The problem I found reading here in the search for my problem - it could be a dozen different things. Start testing and do not replace random parts. That is money that you can save for actually repairing what is really wrong.

The FC is now Running STRONG

I had the Metering Oil Pump (electric) replaced.
Then after it was replaced, it was taken out for a test drive and it still kept limping and the check engine light came on.

So, they scanned it for codes and it ended up being my ECU (N353) that had bad soldering points and it had to be replaced. Took about an hour to find another ECU but then when we found and bought the ECU (n353) $150, it was plugged back and the FC ran beautiful after that!

Thanks to Carlos Lopez for the Advice

You are lucky, mate. I am going to have to chunk down $2K-$4K to get mine zooming again.

a lot of the time when the S5 OMP fails it takes the ECU with it, they were probably both bad, I'm glad you got it working again.
