So, any car buffs that know all about fixing them? Our pathfinder starts (usually, we had one instance where it wouldn't in the past few weeks and had to have the computer reset, it was reading things wrong), but when you press the gas pedal, nothing happens. The check engine light is on. Usually when this has happened we've been able to turn it off, restart it again, and usually within a couple tries it works, but it's getting worse and this morning took a good 1/2 hour to get going. We did recently replace the battery (I was reading online and found someone else that had the exact same problem after replacing their battery). We are planning on getting it looked at asap (meaning today or tomorrow) but I was wondering if anyone had any idea what it was and maybe how much it might cost.
