Frothy? Pretty sure that's not supposed to happen, maybe the oil got contaminated with coolant or something else? That could explain the bad mileage and rough idle.

It's condensation in the dipstick tube, common issue on RX8s, normal.

It's very common, and not a problem.

Been out of touch a bit..

regarding the ECU, the only reason I have replaced one is to deal with a 0610 error when cold. that is the error code for ECU pissed because it is cold.

circuit board medics used to copy the security data from your ecu to a used one. i used them successfully in the past. you just need to be sure the one you have is a good one. The service moves the data, but I am not sure they will warranty your used ECU to work afterwards. I would suggest contacting them though. If they are offering the service for this car, they will warranty it. Mine were time and materials as they worked out the process.

Loki's step is a good one. Let's see what is going on that is pissing off the engine. Also, what I tell my kids is to toss in a can of fuel injector cleaner first thing. I like Lucas.

My ECU was about $750 IIRC, they gave me the motorsports price. cost a couple hundred for the programming. they kept my ECU as a core.

If you decide to try coils and wires, autozone has a lifetime warranty on coils. And their coils are not that expensive.

also, look very carefully at the wires, including the firing order. tech may have looked at wires, but not the order.

So, fuel injector cleaner, and ODBII reader, and provide us idle trims to start out. There is also a good post here for a coil test process with a coil tester. I bought one to chase a problem, but the problem "healed" about the same time the tester came in. your PM stated that you just got the car, likely this is a problem that transferred. Did you do the coils or previous owner? has it always been like this, or is it a recent occurrence?

So here's something interesting... I've had no misfires reported via the CEL for two days now. All I've done so far is top off the oil after noticing it was getting low, and had cleaned the MAF sensor a few days prior (though was still getting the flashing CEL after cleaning it for a couple of days). I hooked up the ODBII reader and cleared the stored "random misfire" error this morning. Haven't done the fuel injector cleaner yet, but will soon!

This morning was my first time using Torque, or anything like it for that matter, so I'm a bit lost right now when it comes to knowing how to get/read all the data. I'll try to figure out how to get the fuel trim data to you when I figure out where it is

I'm too lazy to read back to see if you have done it already, but if you have not, clean the Eccentric Shaft Sensor as well and reset the NVRAM after.
