Honestly I just spent the past day and half trouble shooting a random misfire/rough idle/ stalling/ going into limp mode...I have 2 s2ks right now...i swapped all sensors, cleaned iacv, coil packs, plugs, etc etc...never had a cel flash at all. Pulled the cover off the ecu area gave the harness a good pull and it stopped misfiring. I electrical greased thplugs into the ecu plugged it back in BAM no more misfire. I spent 12+ hours thinking it was a sensor or vacuum line etc etc..was the damn ecu...Im completely stock!

 

nice glad it was a simple fix... sucks you spent the time though

 

Thats for him, I'm still having the issue. Low RPMs 100-300rpms

 

ohh lol... well I still think its your fuel ... if the filter has sedement on it its not going to push the fuel through the line at low rpm... everything is clean like the maf and stuff so I would go with that.. and its not your injectors?!? so i would be looking at that

I guess its time for the tune-up. Plugs, valve-adjustment, fuel filter, clean air filter. It also could be MAP sensor. No CEL

 

doesnt always cell if its dirty .. try and clean it up first and some fresh plugs always help

 

Yeah, last time I did a VA, plugs, and valve-cover gaskets. Car ran much nicer
