So i started noticing that at small load my car's rpms will jump up and down but when i scan it i dont see any missfires and it has not thrown a code for it. I have had a sticking torque converter now for 4 months and thats no big deal to me since im gonna go tim king trans in the next month or so but since i have had this jump in rpms my torque converter will engage and disengage randomly. I checked the wires and plugs and made sure the studs on the coil packs were free of corrosion and also cleaned the maf but to no results. Anyone have any thoughts or things to try and see if it fixes it?
