Was borrowing my sister's 2001 solara SE while I was doing a 2JZ swap on my supra... and the solara started acting up... Obviously shes going to suspect I did something to it... Need some help troubleshooting.
Symptoms:
Under light throttle at nearly all speeds (at low rpm) the car has this tiny little jerk/hesitation. It will have a couple of them at a a time... It feels like a misfire but I'm not exactly sure.. The car is not throwing ANY codes and CEL is off. I was also getting a dipping idle a few days ago, but it stopped doing that.
Knowns:
Plugs are clean, TB is clean, car idles smooth but at 600rpm (assume its somewhat normal) sometimes it will get the jerk while its idling but very very rarely. Gas is clean, car has good compression.
Needs:
I need to know every thing that could cause this type of interruption and not yield a CEL. I can't narrow it down to certain cylinders because it only does it while driving.
So what would cause all the said problems and not throw a CEL? And if I am to test the two coils, is there a quick way I can test it? Anyone have an FSM they can send me?
