My car cranks weakly when I go to start it and it cranks more weakly after it's warmed up. The battery was replaced last week with an 880cca truck battery to compensate for my sound system. Starter and alternator both tested good at advance auto. After the car is warm it also feels like it's misfiring but the plugs and wires are less than a year old. The ecu has also reset a couple times while driving. A few things I suspect may be the problem are: cts, tps, dizzy, or ecu. I wanted to get some input first to see if anyone knows of anything else that may be the problem or if anything I listed is a common problem for our cars.
