I changed the battery last week and now the car idles roughly and sorta shakes, accelerates fair and seems to be fine at highway speeds, it almost seems like the catalytic converter is clogging up. May just be a coincidence, and something else might have gone wrong, but it was running fine before I changed the battery. I have left the battery undone for an hour to try to reset the computer, but that has not helped. Not getting any codes thrown out to guide me in the right direction, anyone have any ideas? Is there a site I can go to get what the normal PCM operation thresholds should be for my car? Thanks.
It has been about a week and a half. But I have had to take it loose twice since the change because I needed to clean the positive cable and didn't have a wire brush when I changed it out and then on Saturday to try to reset the computer. I drove about about two hundred miles between one of those times, how long or how many miles should it take for the computer to relearn the idle and such? TIA!!
