Low Idle/stall after battery unplug
I've run around these and a few other forums looking for answers and I can't seem to find anything concrete.
I just had to replace the positive leads to my battery (2005 tC manual trans.), they got pretty corroded. Had a slight issue with the wondow not working, ghost in the machine I guess, works fine now.
But here's the concerning part: When I turn the engine over, it RPMs up like normal then drops to zero and stalls out. Turn it over again and it runs, but at a really low RPM and if I clutch in too fast, stalls out again. I've disconnected the battery to try to reset and it still happens. If I allow it to idle at a higher RPM by holding the gas in a bit, it seems to get better after a few minutes, but it's still a bit low (600-700 RPM idle)
I plan on soldering the leads to make sure it's a very strong connection, but it looks good (everything else works on battery power too: radio, sunroof, driver window, lights, alarm, etc.). Autozone did a battery check, and it's strong.
Some forums say clean the Idle Air Control Valve, another says we don't even have one and that the ECM controls everything. I might try cleaning the throttle body too? I've got a long drive this weekend for easter, and I'd like to not be stranded in the desert. Your thoughts are greatly appreciated.
