Hi,
New guy here. Been researching for a solution to the TDC PO300 that's being put out. It seems like I've read a million post,but haven't found one quite the same as my trouble.
Just bought this car about a month ago and can't get it to pass Pa. emissions. Car only has 13000 mile on it and runs really well. My problem is the 300 code and it not shifting into overdrive. The mil isn't lit and I thought it might be burned out, but it lights when the ignition is turned on. The hold light doesn't come on when the ignition is first turned on or when the hold button is pushed.
I've changed plugs to autolit and replaced the coil and plug wires, but that hasn't seemed to make any difference. I'm kind of stumped as to what to try next. Any help would be greatly appreciated.
I've read some great advice on this forum already and hope to be an active member.
Thanks!
