Hello gents .. havent been on in quite some time but Ive done some heavy searching for my problem but cant find anything

here is my issue .... driving highway speed .. steady on the throddle ... completely randomly and very suddenly my engine will studder and as fast as it came .. its ok. I could be ok for 10 minutes then I will get a few misfires in a row over a span of a few minutes. Its such a fast misfire and completely random .. im puzzled

Thanks in advance for any and all suggestions

 

What do your plugs look like?

 

I havent looked at them but only have 60k km's on the car (37k miles) ... bad plugs would be just general rough running and consistant misfire ... Im loosing all power for a split second only at highway speed and completely random .. I know plugs are probably becoming due for a change but this is definitely not plugs

 

Well, the ECU is struggling to keep her steady. Air, fire and fuel...you are gonna have to start checking and ruling stuff out. I would pull your front bank plugs (the obvious easy ones) and have a look at them. If you are running a CAI, then I would check your MAF sensor. After that, maybe injectors and subsequent fuel pressure, or O2 sesnors. If you could see why the ECU is correcting, then that would be awesome, since it would lead you to the issue.

 

Check the CEL? Plug, go drive highway, get the code? Still, if you get "random misfire", air, fuel, fire....

 

I havent been getting any CEL ... i might try all the obvious ..clean the MAF and throddle body and go from there
