2G Engine Limp mode?

[onefast2gdsm]

Well took my newly built car out for a drive, I was crusing around 55 mph and my check engine light kicked on, and the car started running like a bag of shit. Looked up the dtc in link and it was a random misfire. I tugged the car along until it was safe to stop, turned it off, cleared the code, started it back up and ran perfect. While the car was off, I unchecked cylinder misifire under the DTC tab. Does the car have limp mode? if not what would cause this? also, stft and combinedft was at 0.0 while it was running bad.

I believe limp mode is more referred to your automatic transmission being stuck in one particular gear. Misfires are most commonly bad wires and or plugs. In case of a new build I would enable the cylinder misfire box on the code reader and drive it to see if the problem is back.

You do not want it to be leaking antifreeze on the plugs causing misfire

Don't think its plugs or wires. I'm using bpr6's and ngk wires, both brand new. After I disabled the check for misfires, it was fine. Time will tell though.

Figured it out, it was a code thrown because if the 1g cas, unchecked cylinder misfire in link and all is well.
