Hi everyone
Having this weird issue that started yesterday. I have a 2018 manifold swapped onto my 15 GT with the IMRC locked out.
The car starts to randomly climb in RPM's for no reason, goes up to 1,500 and stays there for a good second or two before it falls down, sometimes all the way down to 450 before it then finally gets back up to the ~750 mark. Before it all repeats again. Also the RPM's rise like that when I press in the clutch.
Also the revs drop really slowly, both in neutral and in gear. Sometimes DFCO won't even come on and the car will just keep on driving with zero throttle input.
I checked the vacuum lines, which all seem good. Cleaned both the MAF and throttle body. Only things I could think of is maybe a faulty TPS, throttle body, or purge valve.
Anyone had this issue before or someone that could help me? Already talking with my tuner, just checking if someone may already know the cause.
